A.L.
I didn't move my first one out until she was two and the only reason I did that was because I was expecting baby number two shortly there after. My pediatrician said there was no rush if she wasn't trying to climb out so I could have left her there longer but I wanted to get her used to something new since her sister would be needing the crib. So, you've still got time if you don't want to do it yet.
