Look who's standing up!

So I go into get Devin up from his nap yesterday because I heard the mobile playing a little-and thinking to myself "hmmm...." And this is how I found him! The little stink pot pulled himself up! I knew this was coming quickly-and he has yet to pull himself to stand up on anything downstairs besides the fireplace-but it's sure to happen soon. Looks like I need to lower the mattress :) Oh he's getting so big!!
