My baby is a year old. Since last two days he is vomiting every time I feed him and his poop is runny and has acidic smell. Please help.

First of all, feed your baby food that are light on her stomach, like khichdi is the best. Secondly, take her to the doctor as what I suspect is that she may be having some infection which is why her poop is runny and having acidic smell. When my daughter used to have something like this, I used to give her a watery kind of medicine called, Enterogermina, twice a day. It was prescribed by the doctor. And baby Emset along with it for vomiting. I mean I used to give this, before giving any antibiotic. But still in any case, one should not try any medicine on baby without consulting your doctor. Please visit your doctor and can ask about these medicines as well.
