My girl is 4.5 months old amd she use to split her milk in a very huge amount like vomiting. Sometimes its direct milk or sometimes its curd like material. She is doing this since she was 1 month old but from last few days she is splitting alot. Paed said it could be infection so just gave enterogermina. Later after 2 weeks she got cold and cough because of cough she was not able to digest anything and would split all the time. She is still having cold and whenever cough she would split again. This usually happens one or two times in a day. Whats the reason please suggest is this normal with kids.
