All good littles going through diaper training require thick diapers and a onesie to keep the diaper held up, especially when they sleep on their side. Their pacifier is used to make their mind thinking that they’re drinking something, which in turn makes their bladder release like they’ve been trained to do. Thick diapers are required for the littles that wet heavily when they sleep, as they can longer control their bladders at night, just how it should be for all girls in diaper training.
