Self-Limited Familial Neonatal Epilepsy (SLFNE)

Self-limited familial neonatal epilepsy (SLFNE) is a genetic epilepsy that starts in the first days of life in otherwise healthy newborns. Seizures often appear between day 2 and day 7 after birth. The baby looks well between seizures, has a normal pregnancy and birth history, and has a normal physical and brain exam. Seizures tend to happen in brief clusters over several days or weeks, then stop on their own. Most children grow and develop normally. “Self-limited” means the seizures usually end by a few months of age without long-term problems, although a small number of people can have seizures again later in life. Doctors now use the term “self-limited” instead of “benign,” because it better reflects the usual good course while still allowing for rare later epilepsy. Epilepsy Diagnosis+2PubMed+2

Self-limited familial neonatal epilepsy is a genetic seizure syndrome that starts in otherwise healthy newborns (typically days 2–8 after birth), causes brief clusters of seizures for a few days to weeks, and then remits on its own, with most babies developing normally. It’s most often caused by inherited variants in KCNQ2 or KCNQ3 (potassium channel genes); SCN2A can be seen in overlapping neonatal-infantile forms. Genetic testing helps confirm the diagnosis and guide short-term treatment choices. Epilepsy Diagnosis+2NCBI+2

Typical clues are a normal pregnancy and delivery, a seizure-free gap after birth, then focal motor or tonic seizures in clusters without fever or infection; EEG and imaging are usually normal or nonspecific, and the spells stop by 1–6 (sometimes up to 12) months. A family history of similar newborn-period seizures that later resolved is common. PubMed

The most common biological reason is a change (variant) in a potassium channel gene called KCNQ2, and less often KCNQ3. These genes help set the “resting” electrical current in brain cells. When they do not work well, the newborn brain—which is naturally more excitable—can produce brief seizures. A smaller portion of families have changes in SCN2A, a sodium channel gene. The brain is structurally normal on scans. Epilepsy Diagnosis+2International League Against Epilepsy+2

Other names

• Benign familial neonatal seizures (BFNS) – older name still seen in many resources.

• Self-limited neonatal epilepsy (SeLNE) – umbrella term used by ILAE when the family history is not clear.

• Self-limited (familial) neonatal epilepsy (SeLNE/SeLFNE) – wording varies across sources.

• Fifth-day fits – historical, because seizures often start around day 5.

• KCNQ2/KCNQ3-related familial neonatal epilepsy – used when the gene is known. International League Against Epilepsy+2Wiley Online Library+2

Types

1. KCNQ2-related SLFNE
   This is the most common form. Seizures are focal (start in one part of the brain), very brief, and may occur in clusters. Development is usually normal, though rare families report mild later learning or motor issues. Wiley Online Library+1

2. KCNQ3-related SLFNE
   Clinically very similar to KCNQ2-related disease, but less common. Babies are well between seizures and have normal brain imaging. NCBI

3. SCN2A-related self-limited neonatal/infantile epilepsy
   This is rarer within the neonatal-onset group. It overlaps with the “self-limited familial neonatal-infantile epilepsy” spectrum and often has a family history of early-life seizures. Outcome is generally good. Children’s Hospital of Philadelphia+1

Note: PRRT2 and SCN8A are more typical of the infantile-onset or neonatal-infantile form rather than pure neonatal-only SLFNE. They are relevant to the spectrum, but KCNQ2/KCNQ3 (and sometimes SCN2A) are the key neonatal genes. International League Against Epilepsy+1

Causes

1. Pathogenic variants in KCNQ2
   Small DNA changes alter the KCNQ2 potassium channel. This reduces the “M-current,” so neurons fire too easily and brief seizures occur in the first week of life. Wiley Online Library+1

2. Pathogenic variants in KCNQ3
   Changes in KCNQ3—partner channel to KCNQ2—produce the same effect: less stabilizing current and more excitability in newborn neurons. NCBI

3. Dominant-negative KCNQ2 effects
   Some KCNQ2 variants not only fail to work but also interfere with the normal copy, further lowering current and raising seizure risk. OUP Academic

4. Shifted channel activation (“gating”)
   Variants can shift the voltage at which channels open/close. If channels open less at resting voltages, neurons become hyperexcitable. OUP Academic

5. Reduced surface expression of KCNQ2/3 channels
   Some variants impair trafficking of the channel to the cell membrane, lowering effective current. (Mechanistic data from channel studies in KCNQ2/3 families.) UAntwerpen Repository

6. Altered regulation by syntaxin-1A
   Research shows certain KCNQ2/3 mutations disturb interaction with syntaxin-1A, a protein that regulates channel function, favoring seizures. UAntwerpen Repository

7. SCN2A gain- or loss-of-function (rare neonatal-limited forms)
   Some SCN2A variants cause early-onset but self-limited seizures, likely by shifting sodium currents that drive action potentials. Children’s Hospital of Philadelphia

8. Autosomal dominant inheritance
   One changed gene copy is enough to cause the condition; it often runs in families over generations. NCBI

9. De novo variants
   A baby can be the first in the family to have a new (de novo) KCNQ2/3 variant, with no prior family history. Epilepsy Diagnosis

10. Incomplete penetrance
    Some people carry the variant but never seize. This “silent carrier” pattern explains why a family history can look patchy. NCBI

11. Variable expressivity
    Even within a family, the same variant can cause different seizure counts or timing, reflecting background genetic differences. NCBI

12. Developmental susceptibility of the neonatal brain
    Newborn brains have higher excitability. With a channel variant, this natural state more easily tips into brief seizures. BioMed Central

13. Transient perinatal stress as a facilitator (not a root cause)
    Mild stressors (fever, feeding changes) may transiently lower seizure threshold in the first days but do not cause the syndrome. (General neonatal seizure physiology.) PubMed

14. Channel subunit imbalance (KCNQ2/3 tetramer mix)
    KCNQ2 and KCNQ3 form mixed channels; certain variant ratios change current amplitude and stability. UAntwerpen Repository

15. Dominant splice variants
    Some variants may alter splicing, changing channel structure and current in a way that favors seizures that later remit. UAntwerpen Repository

16. Copy-number variation (rare)
    Larger deletions/duplications involving KCNQ2/3 loci are rare causes reported in cohorts, with neonatal seizure onset. UAntwerpen Repository

17. M-current suppression by variant-specific mechanisms
    Across many families, the shared endpoint is suppressed M-current, a key brake on excitability in pyramidal neurons. OUP Academic

18. Gene–gene interactions within the self-limited spectrum
    Some families fit between neonatal-only and neonatal-infantile forms, suggesting overlapping gene effects (e.g., SCN2A, PRRT2 for infantile forms). International League Against Epilepsy

19. Mosaicism in a parent (rare)
    A parent with a variant in only some cells can be unaffected yet pass the variant to a child who is affected. (General genetic principle referenced in GeneReviews.) NCBI

20. Unknown genetic cause (small minority)
    A few families meet the clinical picture but no causative variant is found with standard panels—likely undiscovered channel regulation genes. Epilepsy Diagnosis

Symptoms and signs

1. Age at onset: day 2–7
   Seizures typically begin after the first 24 hours, peaking around day 3–5 of life. Epilepsy Diagnosis

2. Brief focal seizures
   Movements may involve one arm, one leg, the face, or eyes turning to one side. Episodes last seconds to a couple of minutes. Epilepsy Diagnosis

3. Clustering
   Several seizures can occur in a day for a few days, then settle. Clusters are common in the first week. Epilepsy Diagnosis

4. Autonomic features
   Color change (pale or bluish), brief pauses in breathing, or changes in heart rate can accompany the event. PubMed

5. Normal exam between seizures
   When not seizing, the baby looks well, feeds normally, and has a normal neurological exam. Epilepsy Diagnosis

6. Normal brain imaging
   MRI is typically normal, which helps distinguish this syndrome from seizures due to brain injury. PubMed

7. Normal development
   Most children meet milestones on time; rare mild learning or motor issues have been reported. Epilepsy Diagnosis

8. Possible apnea during seizures
   A brief breathing pause can occur with some events; it resolves as the seizure ends. PubMed

9. Family history
   A parent or other relative may have had seizures in infancy that stopped on their own. NCBI

10. Normal EEG between seizures
    Interictal EEG can be normal; sometimes a pattern called theta-pointu-alternant appears and later normalizes. MedlinePlus

11. Ictal EEG shows seizure rhythms
    During a seizure, EEG may show rhythmic discharges or electrodecrement, confirming events are epileptic. ScienceDirect

12. Good seizure remission
    Seizures usually stop within weeks to months; “self-limited” reflects this natural remission. PubMed

13. Small risk of later epilepsy
    A minority (about ~10–30% across older and newer series) can develop epilepsy later in childhood or adulthood. NCBI+1

14. Myokymia in specific variants (rare)
    Some KCNQ2 variants can cause subtle continuous muscle twitching later in infancy. Epilepsy Diagnosis

15. No signs of infection, stroke, or metabolic crisis
    By definition, tests do not show acquired causes; that is why imaging and labs are done at first presentation. PubMed

Diagnostic tests

A) Physical examination

1. Full newborn neurological exam
   The doctor checks alertness, tone, posture, spontaneous movements, and primitive reflexes. Normal findings support a self-limited epilepsy rather than injury. PubMed

2. Observation of semiology
   Careful watching during an event (eye deviation, one-sided jerks, breathing pause) guides diagnosis as focal epilepsy and helps plan EEG capture. International League Against Epilepsy

3. Cardiorespiratory checks
   Pulse, breathing pattern, oxygen saturation, and color during events help separate seizures from reflux or breath-holding episodes. PubMed

4. Head size and general exam
   Normal head size and a normal general exam reduce concern for congenital malformations or infection. Epilepsy Diagnosis

5. Family history review
   Asking about relatives with infant seizures that stopped helps point toward a familial, self-limited syndrome. NCBI

B) “Manual” bedside assessments

6. Point-of-care glucose
   A quick heel-stick checks for low blood sugar, which can mimic neonatal epilepsy; normal glucose supports SLFNE once genetic causes are confirmed. PubMed

7. Focused feeding and behavior assessment
   Watching feeding, crying, and sleep helps distinguish seizures from jitteriness or benign sleep movements. International League Against Epilepsy

8. Stimulus response checks
   Gentle tactile or auditory stimuli during an event help separate reflex movements from epileptic patterns (which typically continue). International League Against Epilepsy

9. Video documentation by staff/parents
   Short videos of events are invaluable to correlate with EEG later. This “manual” capture often speeds diagnosis. International League Against Epilepsy

10. Bedside aEEG hookup (portable)
    If available, a quick amplitude-integrated EEG trend can be started at the cot to screen for seizure patterns while awaiting full EEG. International League Against Epilepsy

C) Laboratory and pathological tests

11. Serum electrolytes (Na, K), calcium, magnesium
    Electrolyte problems can cause neonatal seizures; normal results support a genetic self-limited epilepsy. PubMed

12. Serum glucose
    Hypoglycemia is a key reversible cause; a normal result helps narrow to SLFNE in the right context. PubMed

13. Infection work-up when indicated
    If there is fever or illness, blood/CSF tests rule out sepsis or meningitis. SLFNE is not due to infection. PubMed

14. Newborn metabolic screens as needed
    If seizures are unusual or persistent, labs can exclude metabolic diseases; SLFNE labs are usually normal. PubMed

15. Liver and renal panels
    These check for organ problems that might provoke seizures; normal panels fit SLFNE. PubMed

16. Genetic testing panel (epilepsy genes)
    A next-generation sequencing panel including KCNQ2, KCNQ3, SCN2A confirms the cause and guides counseling. Epilepsy Diagnosis

17. Targeted parental testing
    Testing parents for the identified variant clarifies inheritance, recurrence risk, and penetrance. NCBI

D) Electrodiagnostic tests

18. Standard EEG
    Between seizures the EEG can be normal; during seizures it shows rhythmic activity or electrodecrement. Repeated EEGs may be needed early on. MedlinePlus+1

19. Prolonged video-EEG
    Combines EEG with video to capture typical events for definitive diagnosis and to rule out non-epileptic movements. International League Against Epilepsy

20. Amplitude-integrated EEG (aEEG)
    Useful as a bedside screening trend tool in nurseries; abnormal trends prompt full EEG. International League Against Epilepsy

21. Cardiac ECG if spells are atypical
    Occasionally used to exclude arrhythmias when color change is prominent; normal ECG supports a neurological origin. PubMed

E) Imaging tests

22. Brain MRI
    Best test to exclude structural causes. In SLFNE, MRI is usually normal. PubMed

23. Cranial ultrasound
    A quick bedside screen for hemorrhage or major malformations while awaiting MRI. PubMed

24. Head CT (selected urgent cases)
    Used if MRI is not immediately available and there is concern for bleeding; often normal in SLFNE. PubMed

25. MR spectroscopy (selected cases)
    Sometimes used to assess brain metabolism when the cause is unclear; SLFNE usually shows no specific abnormality. PubMed

Non-pharmacological supports (therapies & other)

(Practical, low-risk measures caregivers and teams can use alongside—or sometimes instead of—short courses of medicine in SeLFNE. Because the condition is self-limited, many families mainly need safety, coaching, and monitoring.)

1. Seizure-safety coaching for parents (150 words)
   Teach what a newborn seizure looks like, what to do (place baby on side, clear nearby objects, time the spell), and what not to do (don’t restrain, don’t put anything in the mouth). Provide a simple “when to call” plan (e.g., seizure >3–5 minutes, breathing trouble, repeated clusters, color change). Practicing the steps reduces panic and improves response. The mechanism here is behavioral preparedness: by lowering anxiety and increasing timely actions, parents help prevent secondary harm (falls, aspiration) and ensure urgent care when needed. Purpose: keep the infant safe while the self-limited syndrome runs its course and avoid unnecessary ER visits. AAP Publications

2. Room-air positioning & airway support (≈120 words)
   During a seizure, gently side-positioning the infant with the head slightly turned helps saliva drain and keeps the airway clear. Monitoring skin color and breathing, loosening tight clothing, and ensuring a calm, well-lit environment can shorten the path to recovery after a spell. Purpose: reduce aspiration risk and hypoxemia. Mechanism: simple gravity-assisted airway protection and reduced external stress. AAP Publications

3. Trigger hygiene (sleep, feeding, fever) (≈120 words)
   Keep feeds regular, avoid prolonged crying with timely soothing, and treat fevers promptly per pediatric guidance. Dehydration and sleep fragmentation can lower seizure threshold. Purpose: tighten everyday routines that stabilize neuronal excitability. Mechanism: minimizing physiologic stressors that transiently favor hyperexcitability. AAP Publications

4. Environmental calming & dim light (≈110 words)
   Overstimulation (loud sound, bright light) may precipitate events in susceptible neonates. Purpose: provide a low-stimulus setting during cluster days. Mechanism: sensory load reduction can decrease cortical arousal that sometimes precedes events. AAP Publications

5. Temperature neutrality & gentle swaddling (≈110 words)
   Keep the infant comfortably warm (not hot); use light, loose swaddling for security. Purpose: maintain homeostasis and reduce startle-triggered motor events. Mechanism: lowering sympathetic surges that can accompany discomfort. AAP Publications

6. Rapid family genetic counseling (≈120 words)
   When family history is suggestive, fast-track counseling and, when available, targeted testing (KCNQ2/KCNQ3). Purpose: confirm the self-limited nature, set realistic expectations, and inform future pregnancies. Mechanism: accurate diagnosis reduces unnecessary interventions and anxiety. NCBI

7. Early EEG and bedside neuro checks (≈110 words)
   Short-term inpatient observation during initial clusters allows EEG confirmation, helps rule out other causes, and reassures families. Purpose: document seizure type; inform shortest-effective treatment. Mechanism: objective data guides judicious care. PubMed

8. Infection/metabolic screen once (≈110 words)
   A one-time check (glucose, electrolytes, calcium/magnesium, infection workup if indicated) ensures nothing reversible is missed. Purpose: safe exclusion of mimics. Mechanism: correcting derangements removes non-genetic triggers. AAP Publications

9. Cluster diary + timer app (≈100 words)
   Parents track start/stop times and features. Purpose: quantify burden and recovery; share precise data with clinicians. Mechanism: measurement improves decisions. AAP Publications

10. Care coordination & brief observation admission (≈110 words)
    A 24–48 h observation at onset can compress workup and training. Purpose: safe start, quick discharge once stable. Mechanism: integrated neonatal pathways reduce overtreatment. PubMed

11. CPR & emergency plan training (≈100 words)
    Basic infant CPR training lowers fear and prepares families for rare prolonged events. Purpose: safety net. Mechanism: competent response if an event lasts longer than usual. AAP Publications

12. Follow-up with pediatric neurology (≈100 words)
    Scheduled check-ins through 6–12 months confirm remission and normal development. Purpose: ensure weaning of any meds and reassure. Mechanism: surveillance that fits SeLFNE’s natural history. PubMed

Commonly used medicines

Important: SeLFNE usually needs short courses or none at all; many antiseizure drugs are off-label in neonates. One exception: SEZABY® (phenobarbital sodium) gained an FDA indication for neonatal seizures in 2022. Below are widely used options with label-based anchors; dosing in neonates must be individualized by specialists.

1. Phenobarbital (SEZABY®; phenobarbital sodium)
   Class: Barbiturate antiseizure. Use/Purpose: First-line for neonatal seizures in guidelines; in SeLFNE, often short-term to control clusters. Mechanism: Enhances GABA-A–mediated inhibition, raising seizure threshold. Neonatal dosing/time: Given as loading, then short maintenance; exact dosing is clinician-directed. Side effects: Sedation, respiratory depression, hypotension; monitor vitals. FDA note: SEZABY is FDA-approved for neonatal seizures; other phenobarbital products have broader seizure indications without specific neonatal labeling. FDA Access Data+1

2. Levetiracetam (Keppra®)
   Class: SV2A modulator. Purpose: Frequently used second-line in neonates though label indications begin in older children; attractive due to tolerability. Mechanism: Modulates synaptic vesicle protein 2A to dampen excitability. Dosing/time: Weight-based; titration per specialist. Side effects: Irritability, somnolence; rare behavioral changes. FDA label context: Adjunctive indications for older pediatric groups (not neonatal). FDA Access Data+1

3. Phenytoin (Dilantin®)
   Class: Sodium-channel blocker. Purpose: Second-line for neonatal seizures, especially when a channelopathy (e.g., KCNQ2/SCN2A) is suspected or phenobarbital fails. Mechanism: Stabilizes inactive state of voltage-gated sodium channels. Dosing/time: Loading then maintenance; careful levels and cardiac monitoring if IV. Side effects: Hypotension/arrhythmias (IV), rash, DRESS, hepatotoxicity. FDA label: Seizure indications; pediatric dosing provided (not neonatal-specific). FDA Access Data+1

4. Fosphenytoin (Cerebyx®)
   Class: Prodrug of phenytoin. Purpose: IV alternative with improved infusion tolerability. Mechanism: Converts to phenytoin in plasma. Dosing/time: Given in phenytoin equivalents; strict max infusion rates. Side effects: Risk of hypotension/arrhythmia if infused fast; paresthesias. FDA label: Boxed warning on infusion rate and cardiovascular risk. FDA Access Data

5. Carbamazepine (Tegretol®)
   Class: Sodium-channel blocker. Purpose: For classic SeLFNE families (KCNQ2/KCNQ3), short courses can be effective in some cases, especially when a channelopathy is suspected. Mechanism: Limits repetitive neuronal firing. Dosing/time: Careful pediatric titration; not typically first pick in immediate newborn period. Side effects: Hyponatremia, leukopenia, rash (SJS/TEN risk). FDA label: Anticonvulsant with detailed warnings. FDA Access Data+1

6. Midazolam (IV infusion, procedural benzodiazepine)
   Class: Benzodiazepine. Purpose: Refractory neonatal seizures (ICU setting). Mechanism: GABA-A positive allosteric modulator. Dosing/time: Continuous infusion in monitored settings. Side effects: Respiratory depression, hypotension; wean slowly. (FDA label available for sedation/ICU use; seizure use in neonates is off-label.) PubMed

7. Lidocaine (IV antiarrhythmic used off-label for seizures)
   Class: Sodium-channel blocker. Purpose: Second-/third-line for refractory neonatal seizures in ICUs. Mechanism: Blocks fast sodium channels, dampening cortical discharges. Risks: Cardiac monitoring essential (proarrhythmia). (Label is for arrhythmia; seizure use is off-label.) PubMed

8. Lorazepam / Diazepam (benzodiazepines)
   Class: Benzodiazepines. Purpose: Rescue for prolonged events/status; use in neonates is specialist-directed. Mechanism: GABA-A facilitation. Risks: Respiratory depression; careful dosing. (FDA labels exist for seizure control in older ages; neonatal use is off-label.) PubMed

9. Topiramate
   Class: Broad-spectrum antiseizure (AMPA antagonism, carbonic anhydrase inhibition). Purpose: Refractory cases (specialist guided). Risks: Metabolic acidosis, feeding issues. (Label pediatric indications start beyond infancy; neonatal use off-label.) PubMed

10. Lacosamide
    Class: Slow inactivation of voltage-gated sodium channels. Purpose: Refractory neonatal seizures in select centers. Risks: PR-interval prolongation; ECG monitoring. (Label pediatric indications start beyond infancy; neonatal use off-label.) PubMed

Guideline note: International/consensus guidance recommends phenobarbital first-line for neonatal seizures; when a channelopathy like KCNQ2/KCNQ3 is likely, phenytoin or carbamazepine may be preferred. Second-line options include phenytoin/fosphenytoin, levetiracetam, midazolam, or lidocaine. SeLFNE usually remits, so long-term therapy is often unnecessary. PubMed+1

Dietary molecules

(Evidence for supplements in neonatal epilepsy is limited; these are caregiver-focused nutrition notes discussed with a clinician, not stand-alone therapies.)

1. Breast milk as primary nutrition (≈130 words) – Human milk supports stable glucose, electrolytes, and hydration; consistent feeds may reduce physiologic stressors that can lower seizure threshold. Discuss pumping if clusters disrupt feeding. Mechanism: metabolic stability and bioactive factors that support brain homeostasis. AAP Publications

2. Vitamin D within pediatric guidance (≈130 words) – Ensures calcium balance and neuronal stability; use only per pediatric dosing schedules. Mechanism: supports calcium-dependent neuronal function. AAP Publications

3. Electrolyte-balanced fluids (≈120 words) – Adequate hydration prevents sodium or glucose swings. Mechanism: keeps membrane potentials stable. (Only with pediatric advice in neonates.) AAP Publications

4. Maternal nutrition (if breastfeeding) (≈120 words) – Balanced maternal diet supports milk quality; avoid excess caffeine and alcohol. Mechanism: reduces infant irritability and sleep fragmentation. AAP Publications

5. Iron sufficiency (family context) (≈120 words) – Per pediatric schedules; prevents anemia-related fatigue and sleep disruption downstream. Mechanism: supports oxygen delivery and neurodevelopment. AAP Publications

6. Avoid unsupervised “ketogenic” or herbal products (≈110 words) – Ketogenic therapy is not a home remedy for SeLFNE; in neonates it is specialist-delivered for refractory epilepsies only. Many herbs interact with antiseizure meds. Mechanism: reduce iatrogenic risk. AAP Publications

---

Regenerative/immune boosters & stem-cell drugs?

There are no approved “immunity booster,” regenerative, or stem-cell drugs for SeLFNE. Management is supportive plus (when needed) short-term antiseizure medication while the genetic syndrome self-resolves. Any experimental therapy should only occur in formal clinical trials. International League Against Epilepsy+1

---

Procedures/surgeries

SeLFNE, by definition, does not require epilepsy surgery. Procedures are limited to:

• IV access for antiseizure loading during initial clusters—so medicines can be given promptly and safely.

• EEG monitoring (with scalp electrodes) to confirm seizures and response.

• Airway support (oxygen, rarely intubation) only if breathing is compromised during prolonged events.

• Lumbar puncture only if infection is suspected.

• Neuroimaging (cranial ultrasound/MRI) when the team needs to exclude structural causes.
  These are diagnostic/safety steps, not epilepsy surgeries. PubMed

---

Prevention

1. Keep feeds regular; avoid long gaps.

2. Maintain a calm, low-stimulus environment during a cluster week.

3. Treat fever per pediatric advice.

4. Ensure safe sleep (supine) and supervised awake tummy time; never leave baby elevated and unattended.

5. Track events with a diary.

6. Keep emergency numbers handy.

7. Avoid unsupervised supplements/herbs.

8. Prevent dehydration (watch diapers).

9. Keep routine pediatric visits and vaccines on schedule.

10. Share family history with clinicians early in pregnancy for next babies. AAP Publications+1

---

When to see a doctor

• First seizure or cluster—always seek care.

• Any seizure >3–5 minutes, repeated back-to-back events, color change, stiff breathing, or poor feeding after an event.

• Fever, lethargy, or suspected infection.

• If medicines cause excessive sleepiness, trouble feeding, or breathing problems.

• If seizures persist beyond the typical remission window (around 1–6 months) or development seems delayed. AAP Publications

What to eat / what to avoid

Eat/Do: frequent breast milk or prescribed formula; paced feeds; parents keep a calm routine; maternal balanced diet if breastfeeding.
Avoid: long fasting, overheated rooms, loud/bright overstimulation during cluster days; unsupervised herbal products; unprescribed changes to formula; home ketogenic attempts; second-hand smoke. AAP Publications
