"Mom, don't you want more ice cream than that?" Jenny peered into Janice's bowl, then into her own, comparing. "No, this is enough for me, thanks." Janice smiled and set the baby monitor on the table with their bowls.

"But Derek—" an older neighbor boy, "—said older kids get more ice cream, 'cause they're bigger. Don't you want more, 'cause you're bigger?"

"I guess my sweet tooth has gotten smaller as I've gotten older. I want less ice cream."

"What's a sweet tooth?"

"It means how much you want to eat sweet things. The bigger your sweet tooth, the more you want to eat ice cream and candy and other sweet things. My sweet tooth used to be bigger. When I was young, I had a huge sweet tooth, like you."

Jenny thought about this. "Why did your sweet tooth used to be bigger, Mommy?"

"Oh, I don't know." Janice grinned. "Probably to keep me eating ice cream so I didn't try to eat you before you were too big to gobble whole."

Just then Jenny's little sister toddled into the room, awake after her nap.

"Run!" shouted Jenny. "Run before she eats you! Her sweet tooth is too small!"
