J has been pretty good at not weeing in his pants since his 4th birthday. We don't quite know why, but he happily went through 2,3 or 4 pairs of trousers a day until his birthday and from then on it has only happened once or twice because 4 year olds don't wee in their trousers. We don't know why, but we are happy about it.
However, he doesn't seemed to have figured out how to not wee in his bed so he still sleeps in a nappy. The problem was that between putting the nappy on and getting into be he would inevitably use it meaning that it needed changing before bed and that habit was getting rather annoying and expensive as well so we made a deal that if he could manage a week without weeing in his nappy before bed he could have something that he really wants:
Isn't that ugly?
