My 4 week old has really runny poop today and he's puking. Not often but he is. And hes super super fussy. What could be happening?
I would take him to the doctor but it’s probably his tummy isn’t agreeing with the formula once you take him to the doctor he or she will tell you maybe you need to switch his formula but don’t switch it until you take him.
@mermaid.mama hes formula fed
