useful

So I think it's official. Lucy is nodding.
Well, she's actually been nodding for a while, but she seems to be nodding yes. Which is not just cute, but useful.
I think this is about the most useful skill in the whole wide world.
Momma Q: Do you want more?
Lucy: Nods, smiles.

Lucy: Unrecognizable hand gesture.
Momma Q: Does that mean "Nurse?"
Lucy: Nods, smiles.

Momma Q: Are you just the cutest, smartest baby ever?
Everyone: Nods, smiles.
