Nancy, Have you investigated how the mother is nursing this baby? I'll bet she isn't sticking to one side per feed, and that is where I would start. Too much foremilk, as has been discussed much of late, can lead to lactose overload or "foremilk-hindmilk imbalance", with high weight gain, lots of colic, and possible green or blood flecked stools. Since mom has a copious supply, you might recommend that she keep baby to one side for 2-3 hrs before switching and see what happens. I'll bet this is the problem, and not allergies! (If I'm wrong, write back!) Good luck. -Lisa Marasco, LLLL, IBCLC [log in to unmask]
