E's favorite game

"Don't call me mom, call me Mommy. You're only 5."
"Oops. I forgot. Mommy!"
"Don't chase after me, and then don't tickle me if you catch me. Okay?"

And then she "runs" away very slowly so that I can catch her and tickle her.

Repeat 15 times.

And that's how you play her favorite game.
