Girls, I don't understand what this hiccup is with my baby - 3 months old. It happens during feeding and she throws up and cries or just can't be fed at all from morning till 12.00. Can't breastfeed or bottle feed. There are no rashes on her face. Damn, it's too early for teeth, do you think what could be the problem?
