My baby vomitted just after milk and now she is not drinking anymore

A. Hi If your child has already vomited ones that you should not offer anything to the child because your child must be already not feeling well if you give milk again then your child will vomit again so let it be just give a medicine for vomiting as of now if your child demands for a feed later maybe after an hour or two then only you give it otherwise just give ORS water and put your child to sleep
