my ds was still doing it at 7- we went to the eurynesis clinic (referred by dr). Woman was brilliant- we did a big chart for him, and also she explained very clearly to him that bladder is a muscle which needs exercising or it will not work properly. He had to do 2 wees before bed- and repeat "I am boss of my bladder!". Within 3 weeks, he was only wetting twice a week instead of every night, and within 3 months was dry. He very rarely has accidents now- usually when he's been reading later at night, and forgets to go to the loo- he's now 10. We still use pullups occasionally if on ho;iday, as I can't be arsed to wash sheets etc. But it will happen eventually!!!! Good luck!!
