DS has been working on pt since end of Dec right before he turned 3. we haven't been really pushy. He easily goes first thing in morning and before bath. Never poop. This week he started going pee at daycare and has been dry for 2 days yeah! Ques is when do i get him in underwear? He freaks out and doesn't want to wear them. Doesn't matter which kind/character. Do i just keep the diaper on and be happy that its dry? I don't mind this taking longer, I just want him to have a healthy outlook on potty!

Re: How to progress to underwear
We just put him in underwear one day. We took him to the store, let him pick out some packages, and that was that. He wears pull ups for naps and diapers for bed time, but other then that underwear all the rest of the time.
He has accidents sometimes, and we deal with them, but it was a lot easier to bite the bullet and make the switch and PT from there.

Sorry I missed that part of your OP. I like the idea of the putting it over the diaper, that way he can get used to the idea.
We also bribed with chocolate.
