2 yr old removing nappy at bed time

[Bexdl]

3 nights in a row now! she's happy to put it and pjs on and go to bed and this evening even tucked herself up under the duvet and went to sleep - it's all fine until she wakes herself up wet and uncomfy which can be at any time. sleeps through and happy/healthy. any suggestions on making the nappy/pull up stay up?!

Is it as absorbent as possible, so a 6+ nappy?

Can you leave a pull up out and show her how to put a new one on?

Have you tried putting it on backwards? It's harder for them to take off

Sellotape all the way round. You need scissors to hand, when you change the nappy, but it is the thing that worked best when my dses did that.

Mine did this, I decided that to avoid it, I made her wee just before bedtime (after the stories) put her to bed without one. Then I go up at around 10pm and while she is asleep I pop her on the potty, and tell her to do a wee, she doesn't wake up but does a big one - then I put a nappy on afterwards. Usually works and her bladder is quite empty then.
