We've got a climber

Lately, Miriam hasn't been going to bed as well as she used to, which I think (hope?) is pretty typical for her age. One evening, about a month ago, after putting her to bed in her "big girl bed" then going through the "letting her cry for awhile and going back in and comforting her cycle" a couple times, we just let her cry until she went to sleep. When we went to check on her before we went to bed, this is where we found her. Remember... she's supposed to be sleeping in her bed now so that Cora can sleep in the crib. Fortunately, Cora was sleeping downstairs in the Pack'n'Play that night. I thought parents usually have trouble with kids climbing out of cribs... she has yet to do that but she's climbed in several times now.
