The other day the word was "Snaffle: To obtain especially by devious or irregular means. I snaffled the last cookie."
I stole Tyson's phone earlier that day and read the word to Eden. She didn't seem to be paying too much attention.
Later on in the day:
Tyson: "Want to hear the word of the day?"
Me: "Oh, I already read it to Eden. Its...umm...snuffle or something."
Tyson: "The word is...."
Eden: "I snaffled the last cookie!"
She WAS listening! That was the example sentence they gave in the app. I can't believe how good that girl's memory is.
