All in One(AIO)

All-in-one diapers (aka AIOs) are a one-step diapering system that is easy to use. They are shaped like disposable diapers and consist of a waterproof outer layer with attached absorbent layers; hence the name "All-in-One." All-in-one diapers are put on just like disposable diapers: Open the diaper, lift baby's bottom, slide the diaper underneath, close the diaper and off you go! Although all-in-one diapers aren't the cheapest option available, keep in mind that they do not need a separate cover so you're saving money there. Many families like to have some all-in-one diapers around for grandparents, babysitters, and for use at daycare.As you see in the picture to the right, this diaper is just as it implies, all in one. There is nothing you need to add to this diaper it has a waterproof outer layer, an absorbent inside.
