I believe can help you solve the problem of your child wetting the bed.
Our 7 year old daughter had a problem with bed wetting. In hindsight, we used "pull up nappies" for far too long. When we took her out of "bed pants" my daughter was wetting the bed on a regular basis, this went on for a few years.
I’m sure you can empathise with the parental frustration of changing bedclothes and bringing the duvet to the laundrette, not to mention seeing the look of self disapointment in our sweet daughters face.
