HI A.,
I also have a child with a milk allergy as well as a peanut allergy and I am also pregnant with my second child. I spoke to my OB about similar concerns a while ago and he said there was no reason to omitt any foods while you are pregnant. When you are pregnant, the fetus does not get the foods you are eating in the same form. A child develops an allergy based on whether or not he/she has the right genetic makeup and enzymes to break down the proteins that cause allergies. I also spoke to my daughter's allergist and he said that it was more important what I ate when I was breasfeeding. My daughter may not have the peanut allergy if I had known not to eat peanut butter when I was nursing after finding out that she was allergic to milk. I now have more info for my second, unfortunately at the cost fo my first. My suggestion is that if you are planning on nursing, omitt dairy, nuts, eggs, shellfish, and soy to help avoid any food allergies. That is my plan even though it is going to be a hard one. On a good note, the allergist also told me that food allergies are the least common inherited allergy, so there is hope for our babies in utero! Hope this helps...I am finding out more and more new facts every day about allergies myself!!
