***Please don't hate me****
I put Jack to bed in whatever is handy, usually one of the same fitteds we use for daytime, and some recycled sweater pants. He never leaks, he is never completely soaked, he nurses all night to boot. He doesn't care if he is wet either.
I do change him when I go to bed, about midnight, then around 7am when I get up. So he isn't in the same diaper for hours and hours like some of the heavy sleepers here.
I will not be surprised if his pee patterns change, but it is pretty easy for night right now.
