My DD still wears a nite nappy and she is 6 and a half. I was a bed wetter too until quite old (maybe 10??) Had some friends over for dinner last night that took their twin boys to a psychologist who "trained" them out of it. Only took 2 weeks for one to stop and 6 weeks for the second one. I am thinking of giving that a go in the summer as I think being 10 and wetting the bed is a bit old and apparently it can take a while to "grow" out of.
