my son is 13 and a half pounds, wearing size 1 pampers. He's pretty much ready to switch sizes though. At night he wears size 2 huggies snug n dry. The last couple of nights he has wet through. Somehow his back gets wet? I don't think you can get size 2 overnights. Anyone have recommendations as to what's good for boys? His wetness all goes to the front so he doesn't end up using the whole diaper.
