How often do you offer the potty?

W is just over 17 months old. We went a few weeks where as long as I offered the potty regularly the only dirty diaper he would have was while he was sleeping so I decided to try the 3 day method (turned out to be 2 and a half days, lol).

We're on day three. Day one we had two accidents. Day two he almost had an accident but we caught it, and day three has started off really well with a big pee as soon as I put him on the potty.

But he still doesn't ask to use the potty, I just offer it a lot.

So how often do you actually offer the potty to your early potty learner?
