right now when my mama can't poop she goes maybe 2 days without pooping and the third day she finally goes so it hasn't really been bad for her but I would definitely go to children's hospital .
really because I pump and the hospital said their supposed to go up to 5 days and anything more than that your supposed to go back in to get checked out.
Breast fed or formula fed? I would definitely call in--breast fed babes can technically go 10 days without pooping but that's on the verge of too long.
nine days?? thats a very long time and dangerous....try tummy massages, you need to apply a bit of pressure. Also, call the doctor, he may need to prescribe something or give you advice
