Stair climbing

Isaac loves climbing stairs. Unfortunately, he often thinks it's a game. He's getting pretty quiet and sneaky with the walking, and if you aren't paying attention, he'll sneak up the stairs on you. When Paul or I find him climbing the stairs he just laughs like it's great fun. He has made it up to the top on his own a few times (he's sneaked past Mommy and Daddy on different occasions). And he's fast too. Often when we hear him, by the time we get there, he's almost at the top. Thank goodness at least he's good at it.
Climb a bit, then stop and pose.

Climb some more...

then turn around and make sure Mommy is still back there.
