It sounds like he's getting an awareness, that's awesome! We had heard the "buckle down" theory, too, but that was hard for us - our work schedules are all over the place and getting a few days to hunker down just didn't happen. So instead we started slow. We put a potty at her favorite table instead of a chair and let her be naked anytime she as home for like 2-3 weeks. Eventually she became fascinated with the "something" going into the potty! And we made the biggest happy deal out of it that we could! Once the awareness kicked in, the rest almost happened on its own. We'd repeat, "Peepee goes in the potty!" over and over and over, and "No peepee on the floor," whenever she had an accident. Once she seemed to understand, we ditched the diapers and never looked back. So many different ways to do it, so you can pick what works for you and your life!
