Hello,
I had a daughter that did the same thing. It was awful. She cried all the time because she was hungry and her tunny was upset. The only thing that worked was solid food. I started feeding her cereal at about 4 weeks. That seem to stay down and not upset her stomach. She just didn't drink a bottle as much as normal babies do. She found a pacifier and that would sooth her. She would still drink soy milk, but not that much. I tried anything to help her when I went through that. She is now 9 and is just fine. Still doesn't like milk much and if has too much gets a tummy ache.
