Pro tip: sleep diapers are worth the cash.
During the day, he wears the cheapest disposables we could find (Target brand).
During the night, the extra cash towards sleep diapers are well worth the expense. Those things could hold a gallon of pee and still manage to keep the poop contained.
I’m not sure how much they are, but I’d wrap his butt in cash money if it meant a little extra sleep.
