When my son generally eats, after one or two spoon of his food showing he will vomit but not vomitting and we are giving drinking water at that time then it's fine. why it is happening?

A. as you make the baby eat baby shows no interest and throw out.. don't force feed or overfeed the baby.. try developing the food interest have meal together add variety and creativity to plate let the baby have his own food start with vitamin supplements as Zincovit or syrup A to Z consulting your pediatric
