We used to be able to wake her before 11 pm,
and have her go to the bathroom,
and she would wake up dry. Then she was still having accidents, despite that. After she turned 6 1/2, we invested in a bed alarm. She is a very deep sleeper, and never really woke up, but after about two weeks, she had 16 dry nights in a row. Then we had some friends visit, and the kids slept in her bed. She wore the alarm, but did also have an accident.
