My best friend's baby had a similar problem with being sick after eating, and it was very upsetting for her, and for the baby. However he does seem to have grown out of it now. I wonder if it was anything to do with just being very little, having an underdeveloped system or eating too much too fast? She did seem to give him a lot of very stodgy food, and rarely waited until he told her he was hungry (by crying). It does seem like your baby has an intolerance though. Does she have certain foods that she copes with well? why not just stick to them for now, after all, no point eating what makes you sick. But do ask the Doc for advice.
