Crying while pooping

M. • “For with God nothing shall be impossible”. 25. Married.

LO has been on formula for almost a week and every time he poops he seems to be in pain. He cry’s and seems to be uncomfortable and the only way to soothe him is by cradling him. His poops are not hard they seem like normal stools and has been having 1-2 bowl movements. Is anyone’s LO the same way? Getting concerned since I might think he could be constipated.
