Overnight training pants are designed with more absorbency than regular training pants to be able to contain accidents that happen at night. Potty training at night can be difficult for many kids and usually takes longer to master. Overnight potty trainers are pulled on and off just like regular underwear, they have multiple layers of absorbent cotton on the inside so that a child can feel the wetness. Potty Scotty and Potty Patty Night Time Training Pants have side snaps to adjust fit when necessary. Mother Ease Bedwetter Pants can contain as much as 21 oz of liquid.
