Sorry to leave you hanging on the whole potty training thing. The weekend of trying didn't end exactly as we'd hoped, as Carter had more accidents the third day than he did the other two.
Oh well, lessons have been learned (mostly by me), and we continue the process.
The good news is that ALL of Carter's class at school are in the process of potty training. (Bless his teacher, right?!?!) He's been doing well with that, and we ask him if he needs to go regularly at home as well. We'll make the official switch to those cool big boy underwear eventually...it just may take a few more weeks! :)
