Just like an All-in-One except YOU get to choose the absorbency you need. Pre-stuff them on laundry day and they are ready to go. This is an overnight favourite.
Pocket diapers require you to stuff an insert into them. They are a bit bulkier, but have the option of adding more layers for absorbency. This is a good choice for an overnight diaper. Simply add a few extra inserts and it will keep your favourite bum dry the whole night.
