My husband cannot for the life of him figure out how to get a cover with a prefold on a wriggling baby's bum without it all unraveling again. So we want to buy about 5 to 7 AIOs for him to diaper our son with, so he can do diaper duty without him losing his mind (he's got work all day, so we're not gonna buy a lot, just a few).

Our boy is a happy little chunk and we've had to get different covers just now bc the old ones wouldn't fit his legs.

So I'm looking for recommendations for good AIOs that will fit big legs. Thanks!
