Hello!!! Girls, can you tell me... My baby is one month old, and after each feeding we vomit. Although I wear a bottle for 15-20 minutes after feeding. It still doesn't help, breastfed - vomited, now with formula started - it's the same thing... Maybe an hour after eating he vomits, sometimes even cries... Has anyone had this? Should I worry?
