Much to my dismay, Zander has learned how to climb up the ladder on the bunk bed. It is completely vertical, so I was hoping that he wouldn't figure it out yet. And it is completely attached. I can't just take it off because it is part of the structure of the bed.I can't believe he is getting so big. While I love how happy and pleased with himself he gets every time he ends up on the top bunk, I do not enjoy getting him down multiple times when the boys are supposed to be going to sleep. The first night he figured it out, we were in there six times getting him down. It's a good thing he's such a cute little stink!
