My Dd is 3.5 yrs and is still wearing pull ups at bedtime. Afew months ago, following regular dry nights, we switched to pants in bed and heaped on the praise etc. What followed was lots of bedwetting (and very disturbed sleep for the whole family). In hindsight, perhaps we should have persisted but with all of us bleary eyed and fed up, we reverted to pull ups again. Friends have said that they made the switch seemlessly and haven't looked back - are we doing something wrong?
