Staring down the barrel of mobility

You're just so darned proud of yourself aren't you?? I went in to retrieve Poops from his nap and this is what I walked in to. He hadn't yet sat up by himself so this was a first for him. After that he wouldn't stop doing it. At bedtime after we read and I put him down, I cracked the door to peek at him, and there I see, his big ol' head in front of the little rainforest aquarium thingy on his crib, sitting up, playing with the bird and the monkeys. And an hour later, after our little game of up, down, come on sweetie go sleepies, up down, up down (I should've known better) he finally tired himself out. Didn't want to waste his newfound talent I guess! I don't know whether to gasp or clap, maybe a little of both, but sweet fancy moses, we're staring down the barrel of mobility! To the babyproofing aisle, troops! Arm yourselves!
