I posted a question a couple of weeks ago, but did not see a response. We started N75 almost 4 months ago. We have used the bell and gate for most of that time as our son won't stay sitting on the potty for more than 2 seconds if not gated. He pees and poops on the potty no problem when gated, but has "accidents" in between. We have moved the bell time down to 30 minutes, have him clean up his messes, and stay gated after an "accident" until he pees or poops on the potty as he is supposed to, but none of these are motivating him to pee and poop on the potty on his own.
