We don't give him solid food. I realize that is a bit more extreme than your looking for though!
Charlie gets very little in the way of food, because his immune problem gives him basically a revolving door of allergies. We know that big ones that he is truly allergic to (fish, shellfish, eggs, peanuts, tree nuts, avocado, papaya, mango, banana, peaches, apricots, anything latex based) but then because his IgE is so high, his body randomly reacts to things. So something he is fine with today could send him into shock tomorrow and be fine again by next week. Much easier for us to half starve ourselves and breastfeed exclusively. Although there are some foods he does have (mostly whole foods) and we're just really vigilant. If we DO make something that calls for something he can't have, but we want him to have it, we just substitute. Plus we have had to cut a lot out of our diet, and we just substitute for everything. The hardest thing to substitute or omit is eggs... they are so multi purpose!
