The sextuplets are turning 3 and the Gosselins are celebrating in true Gosselin style. Super-organized Kate is planning an amazing carnival-themed bash, complete with carnival games, hot dogs, popcorn, funnel cake, a clown and even ponies! How will the sextuplets react to such an extravaganza?

With all eight kids in tow, Jon and Kate visit a local amusement park, Dutch Wonderland. The sextuplets experience their first ride and learn that roller coasters may not be to everyone's taste. Throw in one twin who refuses to have a good time and the obstacles seem insurmountable. But all in all this is a successful family fun day-no small feat!

Mother's Day is here, which means that Jon and the kids work together to give Kate a much-deserved break. Jon prepares a luxurious breakfast in bed while trying to keep the kids from waking their sleeping mom. Kate's pampering continues with a pedicure at the spa. If only Mother's Day came around more often!

Even adults don't like going to the dentist. So major drama is expected when ALL the Gosselin kids spend the afternoon getting their teeth examined. The sextuplets react incredibly well until the bravest of the group has a total meltdown.

July Fourth is the Gosselins' favorite summer holiday. Starting with a local parade, followed by a picnic lunch and finally some time in the pool, this day is sure to be packed with fun ... until the weather decides to not cooperate and puts a chilly damper on the activities.

When Jon has to work late and cancel his weekend trip to the country with the guys, the Gosselins rally the kids for a fun alternate plan involving everyone's favorite-chocolate! A day at Chocolate World should be a riot for the kids, but how will Jon and Kate control their sugar-saturated brood?

We know the Gosselins like to buy things in bulk, so it makes sense that when they want to buy beef, they go buy half a cow! And to show the kids exactly where their food comes from, Jon and Kate take them to Natural Acres, a nearby organic farm, for a field trip like no other.

Two of Discovery Health's most entertaining women are teaming up! Courageous mother of twins and sextuplets Kate Gosselin is getting the chance to meet one of her idols, green living expert Sara Snow. Kate, who realizes the importance of cooking and eating organically, is constantly looking for new ways to do this in an economical way. A family of 10 can leave a lot of environmental footprints, but with Sara Snow's help, the Gosselin family will be able to limit their energy consumption, reduce their waste, eat better and live healthier.

Once again, the Gosselins have outgrown their house, so it's time to renovate! They convert their attic into a new bedroom for the twins and separate the girls from the boys. Plus, no more cribs for the sextuplets-it's time for big-kid beds. How will they do being separated for the first time, and how will they adjust to their new accommodations?

It's a Gosselin day at the zoo! Sure, Jon and Kate feel like their life is a already zoo, but the kids are excited to learn they're off to Pittsburgh to see zebras, elephants, polar bears and who knows what else. But it will be a long day away from home for the family... how will everyone hold up without naps?

Jon & Kate take all 8 kids to Florida's Disney World on vacation.

Never before seen clips from the family.
