They are NOT diapers; they are designed to aid in the potty training process. Training pants are great for containing leaks, but don't mask the wetness. They are designed for child who are ready to start heading for the potty, such as the ability to:
* follow simple instructions * understand words about the toileting process * control the muscles responsible for elimination * express a need to go verbally * keep a diaper dry for 2 hours or more * get to the potty, sit on it, and then get off the potty * pull down diapers, disposable training pants, or underpants
