seems that it is the caesin (sp?) that gets my son. seems yogurt might be caesin free? am I getting that right? but, he still can't digest it... even caesin and lactose free. he is so senstive that he would vomit if my wife breast fed him after drinking milk... or eating other allergic substances. it was hell.
(edit) I get that he will in time tolerate, but need to clear some stuff first.
