my baby has green in vomit

Wow, I can honestly say I have never heard of green vomit! No wonder you took her straight to the doctors, but as long as she is well in herself and eating normally she should be ok. My daughter had green poo when she was about your little ones age and that turned out to be because she was suffering from bad digestion and she had colic all the time, but she was always fine in herself and ate normally and was happy, maybe it could be something along those lines with your daughter?? I ended up having to buy some colic drops to put in her milk and she was on that for quite a while, it maybe something you could look into and colic can start from around that age too.
