Help fellow lactnetters! I have been speaking to a mother of a now 12 week old boy. He has been spitting up forcefully after most feedings since his early weeks, but the situation worsened about 2-3 weeks ago. The baby also reacts the same to bovine-based artificial baby milk (ABM), but has no spitting after a feeding with a soy-based ABM. The mother has been experimenting with ABMs because she is going back to work and doesn't want to pump while there (which is a whole other story and she is aware of possible production pitfalls). I suspected an infant sensitivity to cow's milk (a brilliant deduction considering the history!) and suggested the mother cut out all cow's milk products from her diet. She's done this for the past week, but she has noted no change at all. (We've discussed it may take longer for allof the protein to clear her system--I haven't asked her to do a diet recall/diary, but that may be next.) I've asked her to review events that occurred about 2-3 weeks ago to see if anything might be related to a worsening of the problem. So far the only event was the infant received a second DPT about then, but he had no apparent site or systemic reaction--no redness, fever, etc. If anyone has ANY other ideas, please send them ASAP. With soy ABM not causing a problem, the mother is considering going to that entirely. Thanks. Karen
