Baby, look at this!!

Kirby is quite the cautious youngster. He often still scoots down the stairs and has just begun to walk up them holding tightly onto the rail, of course. He cracks me up when he'll be on just the slightest rise and will squat down as though he is going to jump with all his might, and just when he looks like he will explode off, he gingerly steps down. Last night however he did some real jumping, and he was so excited to share it with his sister.
