Oh help us now

One night this past week (I think it was Tues), Steve took the walker toy Holden has and helped him to walk with it for the first time. He didn't seem all that impressed so we didn't think much of it.
The next day, I was just sitting in the living room with Holden and all of a sudden he crawled over to it, pulled himself up it and started cruising across the room.
He's always so proud of himself when he figures out a new skill - he just beamed away.
