My son Caleb, who is almost 4, is potty trained, but wets the bed at night. I decided to use GoodNites® Underpants because I heard good things about them. He uses the potty before bed and gets up at night to use it. He still has problems wetting the bed at night, but at least we don't have to worry about him waking up wet. Nighttime is the only time I have trouble with him. He has been potty trained since he was 2.
