He’s almost 7 weeks. He doesn’t it constantly like almost nonstop. Just doesn’t seem comfortable
My baby is 5 weeks and has the same problem I got him some baby probiotic drops and they’ve helped him so much!
It may not be constipation, it could just be gas. Try bicycle legs, tummy massage, and colic hold and see if that helps.
How old? It's normal for newborns to do this as they haven't learned how to relax their pooping muscles yet
