I agree with the previous poster...please check with your pediatrician if you haven't already. If the pediatrician doesn't seem to be concerned with the vomiting, then I would guess that maybe you should just hold off on solids for at least a couple of weeks and try again. Also, did you initially start solids with jar baby food? If so, maybe you should go back and just try adding a little rice cereal to some breast milk or formula (not in a bottle though...by spoon)instead. That is usually the first step to solids. Make it really thin at first and then gradually increase the thickness. Maybe your baby's system justs needs time to adjust. The jar baby food may just be too advanced at this stage.
