My son does have SEVERE reactions even to skin contact. The allergist told us
that it has to do with how processed something is: if you rub a small piece
of cheese on his skin, no reaction, if you eat the cheese and kiss him he gets
horrible hives. My advice, bring it back and be wary of everything. My
husband gave my son a bubble bath that had milk in it, not a fun night. I
have seen milk in makeup, homemade playdough, etc... Be careful.
