I have a 6 year old that I am trying to night train. She was day trained by 3, and we have let her sleep in pull-ups until this point. Now we wake her up around midnight to use the potty and don't allow her to drink after dinner. It isn't easy ... she cries when we wake her. She is dry about 1/2 the time in the morning. Luckily, she has a bunk bed, so if she has an accident, she wakes up, takes off her underwear and goes to the other bunk. Good luck!
