My DD2 is about to turn 6.
We carry/walk her to the toilet each night before we go to bed 10/1030ish.
If we forget she'll often wake in a wet bed.
We have a brolly sheet on her bed so if she wets we just change the brolly sheet (we have 2).
We dont restrict drinks she has a drink bottle by her bed to sip from if she desires.
She is just a deep sleeper and we figure she'll sort herself out in time.
