Sorry the previous reply was so short. I know well the frustrations of late potty training. Having worked in Special Education for awhile, I can tell you, there's worse things out there than a kid who still needs pull-ups at night, so celebrate the fact it's only at night. 18 years old and in diapers is waaaay less fun. Given that there's a not- insignificant number of kids out there who wet the bed well past age 6, and our particular family history around this issue, I'm fully expecting to be doing the kid-in-pull-ups at night thing for awhile. Quite awhile. My own kid sleeps so deeply once he's out there's no way he'll wake up to go to the bathroom. From what I've read, you can either drive yourself crazy trying to "fix" it, or relax and let them grow out of it naturally. The middle ground is limiting water after dinner, bathroom before bed, or rewards for a dry pull-ups if its behavioral, not medical. I don't have any answers but I wanted to let you know you're not alone.
