Take 1: Cute, but she didn't want to stand up. That's Daddy's foot in the bottom of the picture as he cajoled and encouraged. Big beaming smiles, but no dice on the standing up thing.
Take 2: Big sis getting in on the act, Daddy holding hand. Still beaming, still not keen to stand up. Nicholas looking interested in what all the fuss is about.
Take 3: Woohoo! Standing up! Nicholas really wants to know what the big deal is, and Isabella is more interested in the faces Georgia is pulling out of the shot.
