Our 4 year old girl is potty trained during the day and in the past several months or so has regressed to wetting her pants 1 or more times a day. She drinks a lot of water from a sport bottle. She seems to either hold it too long while playing and doesn't make it to the bathroom, or she just can't hold it very well. She does go quite often during the day possibly due to lots of water or light/small bladder. We have checked with the doctor for diabetes and tests came out negative. No problems with BM's. Also, we do use pullups at night and realize now shouldn't use. She seems to be one of the very "heavy" sleepers. We need ideas and guidance as to how to proceed. Thanks!!
