hello, my baby boy is now 4 months old. and he still vomiting milk like curd and in water form. please help is it normal or is there any problem. and his growth is good and he is active too

A. Feed your child only on demand which is what is going to be important and still if the vomiting issues are way more but the child is gaining weight and the child is active then it is not a problem but if you need you can consult your doctor once
