I meant to post this a while ago. He's potty trained!
Rowan was almost completely potty trained in May. He was wearing his pull ups, no accidents, etc. Then we changed classrooms. New teachers, new space. Then new sister! The new teacher encouraged us to hold back a bit before putting him in underwear, but by July, he was ready. We bought him some Mickey Mouse big boy undies (since he loves Mickey Mouse and his fave tv show is Mickey Mouse Clubhouse). He has had maybe had 2 accidents since then (maybe fewer). He's doing so well, and we are so proud of him! :)
