For posters looking for cloth for older children, please do hunt around. I had a (very) large 9 year old in cloth overnight, as well as an average 7 sized seven year old. THere are options, and in my experience cloth nappies overnight were much better st containing floods from bigger children that disposable ones were, meaning less bedding needing to be washed.
And yes, nursery store the nappies, in a wet bag. No smells, no fuss. Just pick up the bag along with the child, swap it for a fresh one next morning.
Do also consider reusable sanpro, which also comes in many forms. My eldest dc (has severe SN) now uses reusable sanpro. Much the same - a zipped waterproof bag for the used ones, clean sent in each day. She finds it much easier to cope with (I have period pants for her, not pads), as she could not be independent using disposable pads - not enough fine motor skill to place them accurately, so needed help. So much easier for her now, and no problem washing them, plus better for the environment. Win win all round.
