Hello! Moms, could you please tell me if my 2-month-old daughter is normal when she doesn't walk much at all, just a little bit (she poops). She poops well, but doesn't have enough strength to poop. Because of this, she starts crying and screaming. I do massage and during the massage she poops (every day). Is this normal? Why doesn't she poop on her own?
