I didn't know she knew...

Today Grace told me to "Hurry up!"
We were leaving to pick Jayden up from school and she said:
C'mon Mama, Hurry Up!
But more like:
-Mahn MAMAH! Urriup!
I said:
Hurry up?
She said:
OHHKAY, Urriup!


Then after her nap this afternoon I was being silly and singing to her something like:
Hellllooo Grace! How are you? Hellllooo Grace! Do you want up?
I picked her up while still singing... She was smiling and giggling so I thought she was enjoying it.
She put her hand to my mouth and said:
Stop. (Very nicely, I might add.)
I said:
Stop?
She said:
OHHKAY, stop.
