Food Allergies Treatment

i want to try a find a soultion for this, maybe a pet store that can do this for me?

My son is 4 and a picky eater, since he has an allergy to wheat, soy and milk, the healthier things I could get him to eat, he can’t have. I need some sweet recipes along with regular everyday meals that he thinks taste just like what he’d like to eat. Such as mac n cheese, cookies, or pancakes.

I’ve been trying to get rid of this allergy since I was 6, and jealous all my friends could eat pizza except for me. My choices of cuisine is very limited, and eating dinner everyday at my house is even worse.

Lets get to the point, what can help me get rid of this wheat allergy?

I’ve been growing stronger to wheat over the years, for example, 5 years ago I couldn’t KFC without breaking in hives, but at the moment, I can eat 3 pieces of KFC with very little symptons.

ok heres the short version my son was on enfamil lipil has gas, fussyness, rash, and spit up so doc switched him to gentleasse and it did the same, so we switched him to soy milk the doc said he was having milk allergies.. so he got alot better but still spit up ALOT.. so the doc said he thinks he has acid reflex so she put him on acid reflex meds zantac and i knotice a huge difference.. but she also switched him to nutramigen… BUT HE WONT DRINK IT HE HATES IT I GOT HIM TO DRINK 2 BOTTLES OF IT IN 2days AND hes still pretty fussy and farts alot… the doc is closed for a week due to remodeling and im not happy with my son not eatting the bottles should i go back to prosobee and the acid reflex medicine or what?
ALSO A LADY RESPONDED TO ANOTHER ONE OF MY QUESTIONS AND SAID “? You need to have an actual allergy test done. Of course he is fussy! Nutramigen is a milk based lactose formula and Prosobee is SOY based, causen protein lactose free formula.” what exactly does that mean…
OH LORD IM A RAMBLER, and i said this was the short version. lol..
THANKS
