Kate Plus 8

There's one thing Kate and Jon Gosselin's eight kids won't be doing this summer, and that's watching their reality TV show's season premiere.

The two-hour debut episode of "Kate Plus 8" (sans Jon) airs this Sunday night on TLC, and a source tells FOX411.com that the kids "won't watch the show when it airs. Kate trusts the producers, but she does like to see the shows before the kids see them. [Plus] she talks about the divorce and her tough year in the season opener."

A lot has happened to the Gosselins since last season.

Jon and Kate got divorced.

Jon hooked up with the daughter of Kate's plastic surgeon.

Jon hooked up with a tabloid reporter.

Jon hooked up with a skiing enthusiast.

Kate starred in, received a lot of bad press for, and was soon eliminated from 'Dancing With the Stars.'

And those are just the highlights.

But things are finally back to normal, or as normal as they can be if you're a member of the Gosselin family.

A source close to Kate Gosselin gave FOX411.com the inside scoop on the family's life post-all-of-the-above. Kate and the kids are back living their life in front of the cameras while dad Jon is behind the scenes, spending occasional days and weekends with his children in their Pennsylvania home.

"Kate has been in high spirits lately. She's excited for 'Kate Plus 8' and the kids really are happy to be back with their crew," said the insider. "The [crew is an] extended family, and the summer is off to a big bang. They're filming a lot outdoors and Kate is showing a lot more of herself in the new show."

After the uproar over the show last season, and hearings in Pennsylvania over whether they had violated child labor laws, there are changes in the shooting schedule this time around.

"The crew spends a lot of the day with Kate alone while she works and handles her daily chores for the house and kids. Aaden, Colin, Maddie, Cara, Hannah, Leah, Joel and Alexis are still a huge part of the show, but they spend less time filming and more time playing and doing homework off-camera," the source said."It's a great trade-off. They love the crew, but the filming is not invasive to their lives. There are some fun vacations planned throughout filming and the kids are happy about that."
