So my little guy has always been a multiple poops per day baby. He turns 4 months tomorrow and he hasn't pooped since Tuesday. On Tuesday he had his usual 2 to 3 blow out poops and nothing yesterday or today. Normal?? Is his digestive system maturing?? He has lots of wet diapers and has been nursing pretty frequently while awake, every 1 to 2 hours since he sleeps 11 hours at night without waking.
