The Biermanns head to court, but this time it's for a happy occasion -– the girls' adoption is ready to be finalized, and with the near completion of their new house, the family is looking forward to finally getting settled. But settling into a routine may be far from reality when Kim and Kroy start thinking that their dream of having a little girl may come true sooner than they expected.

The Biermanns welcome two new additions to their fast-growing family with the birth of twins, Kaia and Kane. Kim and football player husband, Kroy, need a game plan for managing the chaos in their new dream home. With two teenagers and four in diapers, it's also time for a birth control plan.

While Kim juggles caring for Kroy and six children, she also has to manage her nutty assistant, Sweetie, and eccentric nanny, Lana. In an unfortunate accident, two-year-old KJ fractures his leg, landing him in a full cast -- and his nanny, Lana, in the doghouse. Sweetie is put on a quest to find a new housekeeper and pool boy.
