Boolean logic

I've seen the parenting advice of giving the kid a choice to limit options it a lot of places, so I tried it on Mag yesterday when we were about to cross the street. She has two pieces of "gravel" that she likes to carry around, but I have to hold her hand crossing the street. So I ask her, "Do you want to hold the little one or the big one?"
"Little one AND big one!"
"No, Mag, you can hold one rock -- the little one OR the big one."
"Two! Hold two -- little one AND big one!"

Conclusion: now, armed with NOT and AND, she can construct any truth table she needs.
