Large spitups / vomit?

Kelly

Our baby is 3 weeks old and has had a few episodes of large spit up or vomit. It's large quantity and she gets very upset after. We are seeing the pediatrician tomorrow.

She's exclusively formula fed and we've changed formula Saturday to gentle ease. We try to keep her up right in feeding and keep her up right 20 minutes after plus lots of burping to help.

Any advice?
