This was the cutest thing. I really did love Eleven. Honestly, though, I could see Nine doing this, but only if they were younger kids. Actually, I could see any Doctor doing this because I'm pretty sure the Doctor loves children.
Oh I love her so much. I really hope that this is the season when the Doctor suddenly says " Oi! I just figured out how to let Donna Noble remember everything without killing her!" :)<<<<< that last bit would make me the happiest Whovian around
