C.S.
S., I've had this problem a lot with my son and it was a major problem when we gave him a bottle at bedtime. I started giving him his bottle about 30 minutes or so before bedtime, because he would probably wet just a little before that, and then I pull his diaper way up in front. I make sure there's still coverage in back, but in front the sticky tabs are at the very bottom of the picture section. Also, if he's borderline on diaper size you might go ahead and go up. They'll be a little big, but he'll have more wetting area. Other than that, you'll probably just have to deal with it for a couple of months until you break that bedtime bottle.
Good luck!
