Cassie, you may find as he gets a little older he is less sensitive to some of the other things. (garlic, other vegetables) My S-MIL is allergic to citrus, including raw tomatoes. She is ok with tomatoes if they are cooked (spaghetti, chili soup) though.
Do you think the pulling off could have anything to do with him not liking the way your milk tastes after eating certain things? Although I think the flavor variation would be so small, so maybe not?
You may find that as the Prevacid continues to heal his tummy, the burn with eating will go away and he will nurse better. The longer you nurse him and are dairy/soy free, the better his tummy/gut will heal too. Even if you aren't getting blood (yet) in the stools doesn't mean he isn't MSPI. It takes time and exposure to get the blood, but some moms on the mspi board report no blood ever.
Yay for losing the weight, doesn't it feel wonderful?
And yep on the expensive formula, I am almost glad it is so expensive because it is a deterrent for a mom who will/can nurse. This time will fly!
I lived on salads, sandwiches and dairy/soy free soups for lunches, and got creative for cooking dinners. It is harder and harder to be soy free because of the high protein diet craze, soy protein is added to sooooooo many processed foods.
