After a big fight with their mother, identical twins Jessica and Elizabeth Wakefield come up with a brilliant way to show her that being a kid is no piece of cake: they decide that she should give it a try. To their shock and delight, their mother agrees! The twins will get to be their own mothers, while Mrs. Wakefield will be a kid.
But the twins soon discover that parenthood is exhausting - who would have guessed Mrs. Wakefield would be such a messy, mischevious kid? Jessica and Elizabeth decide to trade places again - but their mother says no! Are the twins stuck being their mother's mother forever?

Moms for the weekend . . .

Jessica leaned forward with excitement. "Why don't we trade places? I mean, right now? You be the kid, Mom, and Elizabeth and I will be the grown-ups. You get our projects done by Monday, we'll get your project done by Monday. In the meantime, we get to run the house. Think about it, Lizzie," she continued, turning to her twin. "We can stay up as late as we want, we get to plan our own schedules for the weekend, we can watch TV all the time and buy the food we want." She shivered with anticipation, then gave her mother a sideways glance. "But I bet she won't do it."
"Fine," Mrs. Wakefield said, crossing her arms in front of her.
Jessica couldn't believe her ears. "You mean you'll do it?"
"I just said so, didn't I?" Mrs. Wakefield told her. "If you're sure being a grown-up is so easy, this is a good weekend to try it."
