In each episode, two mothers with very different types of households swap lifestyles and children in a week-long challenge. In the first part of the swap, each mom moves into the others home and adopts their new celebrity family's lifestyle, no matter how different it may be. They agree to follow a manual written by the departing mother that sets out the rules of their new household - how they parent, manage their social life, do house work, unwind and more. In the second half of the week, everything changes. The new moms take charge. They introduce their own set of rules and get to run the new household their way. It's a radical shock to both celebrity families. The results are explosive, enlightening, emotional and often very funny. At the end of the show, the two celebrity couples meet for the first time.
