My dd is about to turn 4yo and we have recently ditched the pull-ups due to the fact that she was starting to get a few dry ones.
Anyway, I started off lifting her at 11pm to help her get through the night without an accident and it has become a habit as she ALWAYS does a wee at this time.
I know she can go 12 hours without one as she will often will then not wee until 11am the following day. Obviously it would be better if she did 7pm-7am but I'm not sure how to manage this transition.
