My kids love to hide underneath blankets, so that they look like little rocks under the blankets. Then they ask me to say, "What are these strange rocks?" over and over again. I'm supposed to finish this playacting by "stepping" on the rocks (very gently) and then tickling the little rocks until the kids pop out from under the rocks.

So random, right? But seriously, we do this at least half a dozen times a week - if not more! It's something we did one time and the kids loved it, so they ask for it over and over again.

Is there anything your LO(s) ask you to do over and over again?
