They’re no more sanitary than changing any diaper! Typically, it’s recommended that you start off the training process with a bowl potty that has a base. This will help to orient your child’s center of gravity and of course fit his or her body more easily. Then, as time goes on, they can graduate to the potty seat attachment to a standard toilet seat bowl. Of course, when dumping out waste take all of the necessary precautions and be sure to scrub the bowl thoroughly using both Clorox and Lysol Disinfectant.
