Is it possible for a child's intolerance to just disappear? My 4 year old has had cmpa since he was born and only ever managed to tolerate a malted milk. We stopped trying the milk ladder until this summer as he kept going backwards. However he tried some sponge cake and didn't have any nasty side effects apart from smelly wind, and he's been helping himself to milky coffee which I stupidly left out on the side, and again hasn't had any symptoms?
I'm really hoping this is the start of him being tolerant, but I just don't know if it can disappear that quickly ?
