My daughter has mastered potty training during the day. She does not need a diaper, she tells us when she needs to use the bathroom and has gone more than a year since her last major accident. That is during the day, though. At night – and naptime – she needs to wear a diaper because she will likely go to the bathroom. She complains every time we put it on, saying she hates wearing it and begs us not to wear one. We fight back because any time we’ve given in and let her try to sleep without a diaper, she ends up wetting the bed. We expect this. Potty training at night is a different animal than during the day. Our daughter is asleep, and her body is not trained to wake her up if she has to go. As a result, she still needs a diaper.
