Thinking about doing a no diaper day from now until around like 7pm. So only a few hours since it's 4:30. But how often should I be taking my son to the bathroom to put him on the potty. He doesn't tell me when he's got to go but he does tell me afterwards and he is interested in sitting on the potty but we always seem to be getting there when he doesn't have to go.
