So exhausted. The past three nights my newborn has been waking us both up because he'll make grunting sounds in his sleep like he's waking up but he's actually just trying to poop. So he'll toss and turn for at least two hours while making sounds in his sleep

Any advice? He does this and makes these sounds for hours and still won't poop till way later. I just let him lay and fart for thirty minutes and changed his diaper and it was clean of poop
