If your wife needs some emotional support relating to the diet she is on (it's hard, for a while I was eating nothing more than organic turkey and potatoes and my daughter was *still* reacting), there is a board http://kidswithfoodallergies.org/eve/ubb.x/a/frm/f/9080095433
, that offers support to women who are breastfeeding food allergic children.
I wish I could help you. And I wish you could help me. I look forward to your update after your visit with the MD this week. Take care.
