All-in-One Nappies are used just like a disposable...except that you wash them rather than throwing them away! All the components are already together making them really simple to use. They are very similar to a pocket nappy, but are already 'stuffed' for you.

This does mean that they take a bit longer to dry, so it's not a good idea to use AIO's exclusively if you don't have a tumble drier. However, they can't be beaten on their ease of use, so definitely worth considering for when you're out and about.
