Excessive spit up

Jocelyne • Mother to a baby boy 💙

Baby is 16 days old and he is only eating formula right now (Enfamil Infant) and after every feeding he is spitting up. At first it was only a little bit so I figured it was normal but it’s gotten to the point where he is spitting up large amounts of milk after feedings. He’s extra fussy and also doesn’t poop as often anymore. Will be calling doctor tomorrow morning to try and get him and appt but has anyone gone through anything similar?
