When to Stop Nakedtime
As great as nakedtime is as a teaching tool, there will come a time when it won't be as useful. If you feel like no headway is being made, you can discontinue the sessions or put them on hold for a while to try some other strategies.
There may also come a time when your child (often the boys, purely for physiological reasons, but this does also happen with girls) starts to spray or play with their waste. Although this can be aggravating and just plain gross, it may indicate some success in your teaching method. If your son or daughter is engaging in purposeful peeing or pooping, that should be evidence that the child understands the mechanics of the process and has some element of control. Parents don't need to get into a big fuss about the mess, but we would suggest restricting or eliminating nakedtime at this point—it will have served its purpose for potty training and will instead deteriorate into peeing or pooping just for fun, or to press parents' buttons.
