Nearly 3YO daughter. Night learning couple months ago and within weeks' time was getting it. After about a month was mostly dry. Couple times would start to wet, only have to change panties because barely started to go before would catch herself. Very upset w/ herself though. Now past 4 nights has soaked, doesn't seem to care! Will wet and sleep rest of night, wake normal time/happy. Is this defiance? What to do now?
