My daughter has been night-potty trained for over 2 years now, and has always and consistently been able to wake up in the middle of the night and go to the bathroom if she has to pee. In the last week she has wet her bed 3 times at night, and I am perplexed by this. The first night she woke up b/c of the wet bed, but other two nights she slept right through the bed wetting until I discovered it when I checked on her before I went to bed. I know this is common, but it just doesn't follow with her prior habits? Could it just be that the air conditioner in her room is making her go ( it gets pretty chilly after being on for several hours)? or could it be anxiety of starting kindergarten in September ( she seems excited, but...)? or could it be some sort of kidney/bladder problem or infection and I need to take her to the doctor?
She also has had a couple of incidents where she has peed in her underwear a little when going to the bathroom during the day (like not getting there fast enough).
Please share any experience with this, including possible reasons, ways to stop it, and how to get urine out of a mattress ( my waterproof mattress pad has failed me 2 out of the 3 nights)?
