Georgeanne: there are two excellent ped g.i. on this list and they certianly can address this with expertese than i but... while the thought is that dairy or soy can be causes full clearnace from the system of dairy protein is, from my recollection, approximately one month. while time consuming and difficlut to start out eliminating both of these is doable.. and survivable. one thing that helps is finding a kosher market or section of a larger market... the laws govering kosruth are such that there should be extensive labeling... ALL product marked PARVE should be dairy free. unfortunately some allow in lactose so PLEASE read carefully. nutritient once received from dairy can be made up in other ways. there are a number of exceelent list of the calcium content of foods. as for the bleeding... there are many known and unknown reasons for blood in the stool... both red and brown. many of the causes are difficult to identify. this is an important time to look at the WHOLE baby and see how the baby is doing overall...
