Thanks, mommies, your advice is so valuable AND appreciated. I'm going to try and do a gradual withdrawal. I think he's ready for the 2 to 1 nap, but I'll try the gradual withdrawal first. I also think - like you said, DebLillian, that he hates something in his room, too. According to my mom I couldn't sleep without a light from a very early age so he might be like me. I think I'll add a bumper too.
Again, ladies, THANK YOU! I'll post again in a few days to update you.
