Kate and her litter of 8 are back for more televised drama -- and it's "nerve racking" for Mama Gosselin.
In a clip from her new special, "Kate Plus 8," the Gosselin matriarch takes the kids on a vacation to Orlando for the sextuplets' sixth birthday.
According to Kate, the vacation -- a first without "her helper" Jon -- was a setup "for disaster."
See the kids in "meltdown" mode when the 2 hour special airs June 6th on TLC.
