Poor little man! what a long list! and poor you too.
Is he growing well? I hope you are you with a good pediatric allergist and that they are supporting you in this as it sounds like it must be really tough.
I thought my DD's list was bad. She had her first allergic reaction at 6.5 months to a baby rusk. SHe reacted to the wheat in it.
After then, like you it seemed like she would react to nearly everything we tried. Weaning was a very scary experience for me as her first reaction was a bad one.
she's allergic to:
Wheat
Eggs
Tree Nuts - all
Legumes incl. Peanuts, Soya, Peas, Lentils, Mung Beans, Chick Peas, Kidneys beans etc.
Sesame
Ginger
Rapeseed
Aveeno Cream
Tree Pollen (although I think also grass pollen)
Cats
Dogs
She is 4 years 10 months old and so far hasn't shown any signs of outgrowing her allergies. I find it all really really difficult as I am not a very good cook at all and feed my kids the same 2 or 3 meals day in day out. But DD is growing well and her allergist says that that's a good thing. We have to carry 2 epipens always and she has 2 types of antihistamine, Piriton for emergencies and NeoClarityn for viral urticaria and hayfever.
Sorry you're having a wobble. It's just so tough isn't it. I'd say we don't have a 'normal' life at all really but I hope everyday that one day DD might out grow some of these.
Sending you and your DS a virtual hug. xxx
