Where does she learn these things?

I went upstairs to see if I could get my two-year old to nap. She had been sitting in the crib for almost an hour, talking and playing but not exactly sleeping.
“Clara,” I said. “Why didn’t you go to sleep?”

“I tried to go to sleep, Daddy,” she said. “But I was freaking out.”

I have no idea where she learned this phrase, but it was enough for me to pluck her from the crib.

It’s unrealistic to think that anyone could sleep while freaking out. Right?
