This kid!
He's pretty much obsessed with his sister. He loves being near her and giving her kisses and he's becoming softer with her, although we still have some room for improvement :) I'll set her down and then magically he's right next to her! I think Rose girl is slowly starting to warm up to him too. I've taken a million pictures of the two of them, but here are some recent ones that perfectly exhibit his love for his sister!
