Hallo, my 5 week old baby is constipated. he is crying as if he is in pain. he has no fever. any advise?

Depends: Straining or irregular stooling doesn't mean constipation.The 5 wk breast fed kid may go 7-10 days without a stool or poo a little at each meal.As long as it is soft, i don't consider that constipation. If the kid is putting out dry rabbit pellets or stool bigger than your finger you can sometimes tease a stool out using vasaline on a q-tip inserted to the length of the cotton & worked around.
