The mom's lactose intolerence was probably triggered by overindulgence in dairy which is partly caused by the WIC programs provision of lots of milk, and cheese, and the mother's enthusiasm for other dairy products. The nursing has nothing to do with mom's intolerence, but she ought to watch the baby for signs of milk allergy. Things like, gas, eczema, pimples, colic, etc may be caused by the uptake of large bovine proteins from the mother's intestine which get into brmilk. M.
