A sign of what's to come?

Do you think this is a sign of things to come?

We are starting to think about getting Jocelyn into a big girl bed in the next few months, if not by her birthday.  She hasn't really shown any interest in escaping the crib yet, but this was a new sign yesterday!  Her crib can become a full sized bed, and though it might be a bit big for her small room, I think that may be what we're going to do.  If she makes it to her 3rd birthday without climbing out on her own, then maybe we can do it for her birthday as a big girl transition.  In the meantime, I think this may be an indicator that we need to be prepared for anything!
