Kushies Ultra All in One Diapers 5 PackKushies Ultra diapers are all in one diapers. They are babysitter friendly and perhaps one of the easiest diaper systems to use. Just place the diaper on your baby and attach it with the hook and loop velcro closures. They are made of 100 cotton flannel on the interior and have a vinyl waterproof exterior. They have a built in flap for greater absorbency and a quicker drying time. You will need doublers for nap time and nighttime if you have a heavy wetter. If you use Kushies as your only diaper system you will need at least 8 for Toddlers and at least 12-15 for younger babies each day.
