Disposable nappies for older child (bigger than supermarket sizes)

[AngelDog]

My 6 y.o. still needs nappies at night, but the biggest size 6 supermarket nappies are too small for him now and we have constant bedwetting which is doing my head in. Where can I get something bigger? Disposables work better for us than cloth, and he weighs about 57 lbs, I think.

Dri-Nites - come in size 4-7 and 8-15, usually next to nappies in large supermarkets.
I'd look to buy online but Amazon's deals are often unclear how many are in the bulk packs.

You move on to something like Drynites pyjama pants, available up to age 15, though supermarkets often don't have them on the shelves beyond about age 8. Readily available in all sizes online.

Great - thank you!
