Quick post if anyone is around now. DS tested + for mild egg allergy aged 9 mo before he ever ate egg. Had never eaten egg at test aged 13 mo when he tested -ve. Been slowly and haphazardly introducing egg, baked no probs, then we started scrambled with a tsp this wind folowed by about 2tsp next day, no probs. today I gave him a tblsp and now half an he later he has these tiny bumps around his mouth. The only appeared just now, half hr after lunch, before he went down for a nap - he's asleep now and I don't know what to do. Wake him for piriton?
