The Gosselins grow another year older, which means that they can handle more fun than they have before! And it s a good thing because for the Gosselins, it's a monumental year. Not only do they plan for the biggest vacation of their lives, but they also begin making plans to relocate their family to another state and build a home that can finally accommodate their 8 growing kids. But first they must get through the sextuplets fourth birthday, the twins 8th birthday, second grade, and the beginning of pre-school for the sextuplets! Jon and Kate continue to amaze themselves and everyone else by accomplishing things no one ever thought possible with 2 sets of multiples.
