So I was a bedwetter for several years. I don't remember when it stopped, sometime around age 10 I think. But that's not the important part. Yah see I would use my pullups on purpose and sometimes put off changing because I was lazy. Now the thing is I didn't stop wetting until I decided to quite wearing the pullups. One night I didm't put one on, and I woke up dry. This went on for several nights. So my theory is that I may have inadvertently, partially diaper trained myself.
