This is a neat site for specifically for kids about bedwetting: http://www.kidshealth.org/PageManage...icle_set=22283

I also read that bedwetting is more common among boys than it is girls.

At least your son is not like my nephew who is 4 1/2 and flat out refuses to use the potty. Actually, I think he just started to pee in it, but he still won't poop in it.
