Hi, wetting the bed really isn't that big of a deal. I personally peed the bed until I was 10 and so did my husband. My son did until he was 7 and now my 8 and 2 year olds are wetting the bed on a really frequent basis. For the 8-year-old we bought her an alarm from E-bay that sounds when her underwear strts to get wet and we have started a daily pee chart in which she is rewarded for not peeing the bed but, we do not punish her for peeing the bed. It is important that you know as a parent you will only make the situation worse for your child if you punish them for wetting the bed don't ever punish them for it.
How old is she? And what is she doing that you don't like?
