We had LO on nutramigen and he kept getting rashy and swelling. I took it upon myself to find a formula with no DHA/ARA. He did well on it, for a month. Then we went to actual allergist and they said he was allergic to milk, eggs, wheat, soy and peanuts. LO is almost 5 months. So, fine, we switched off of the natures one dairy based wit no DHA or ARA. And on to similac alimentum. After 6 days, he has the symptoms all over again! My gut tells me this isn't working..... Went to reg pedi today and tried to explain it, but he brushed it off. So frustrated! Feel like I'm giving him poison and of course it's Xmas week, so not too many dr.s open. Any thoughts?
