Before your child goes to sleep, lay down one or both of the overlays on top of the sheet. When the bed is wet in the middle of the night, just pull of the the overlay. These help with the transition from disposable pants to cloth underwear by decreasing the laundry burden! Choose from the flat overlays that lay smoothly on the sheet or the tuck–in style, with 18 inch flaps of fabric sewn on each end of the pad. These tuck–in tails allow you to secure the ends of the pad between the upper and lower mattress – nice if your child is a restless sleeper. Designate a flat or tuck–in standard (twin) or large (full or queen) overlay, depending on the size of bed your child sleeps in.
