I found the only way was to go 'cold turkey'
I stopped the pull ups and said no- more, invested in more sheets and a waterproof matress cover.
Wee before bed, and every hr until you go to bed,then 2hrly - means waking like when she was a baby....
the next night make it every 1 1/2hrs, then evrey 2hrs, etc etc
within a week or 2 she should get up once a night when you go to bed.
stop all drinks after teatime meal too - no bedtime drink unless its a small sip.
Tell her when shes dry she can have a friend for a sleep over - maybe that will be some help.
