Hi I'm not sure but I think my 15-1/2 month old son may have some allergies. He has developed a rash on his cheeks. He has also thrown up a few times (5 times over a 18 hour period last weekend and twice last night). I figured he's just sick. Then I thought maybe I shouldn't be so accepting (no fever and he's bright eyed and energetic afterwards). He drinks cow's milk. What do people use in place of milk? I read Neanderthin but the replacements in there are just to time consuming (drying meat). PATRICIA TAFT
