Hello. Baby is 2 months old. For the last 5 days, he hasn't pooped on his own. Only burps. He has gone potty once by himself. We did enema and suppositories once. The belly is soft. He doesn't cry. Has anyone had this? Is it like he's collecting poop? Or maybe not eating enough? Please tell me what to do.
