It is so sweet when they play together. I love when I can hear him trying to get her to think about what she is doing. "Here is a corner which has two straight sides. Can you see where it goes?"
It is especially sweet when he does girly things with her, like work on this My Little Pony puzzle. It's not like he actually enjoys My Little Pony... right? It's not like he watched it when he was little... ehem.
And now for something completely different:
Adelaide has such a sweet face... and look at those rolls!
