I guess my best advise is the whole "all or nothing" take. If you decide it's time to potty train then do it with no more diapers. It's underwear all day no matter what. If after a week or so he just isn't getting it (peeing all the time in his pants and doesn't seem to care) then he's not ready and back to diapers and try again in a few months. I had a friend who tried training her boy at that age and it didn't work but she was one who would put him in undies for a few hours then back in a diaper etc. So he just wasn't getting the message. Night time is different you can do pull ups cause it's a different part of the brain that learns to hold it all night. Unless he already wakes up dry then he should be fine with that. With my daughter I also just gave her an m&m for pee and 2 m&m's for poop. She did really well and after a few months she didn't even want the candy so I didn't have to break that habit.
