- wheeze/chronic cough
- rarely angioedema/anaphylaxis
Usually clinical, but if needed:

- -> both type I/type IV can occur
Formula fed:
- Extensive hydrolysed formula if formula-fed
- amino acid-based formula if severe/still reacting to eHF
Breast fed:
- continue breastfeeding
- eliminated cow’s milk from maternal diet and consider calcium supplements
- eHF when stop breastfeeding until 12 months

Management of febrile convulsions?
Chance of epilepsy?
Any kid with first seizure admit to paeds
Risk of further = 1/3
If recurrences, teach parents to use rescue meds - buccal midazolam or rectal diazepam. Phone ambulance if >5 mins
Regular antipyretics = no benefit
2.5% chance of epilepsy in general public
Febrile convulsions alone raise this slightly
febrile convulsions + complex seizure + neurodevelopment disorder = 50% chance
Complex = 15-30 mins, focal, or repeat within 24 hours

Female:
- usually idiopathic/familial, follows normal sequence
