Kate Gosselin managed to keep her family's career afloat last week -- by taking the kiddies on a birthday trip right out of the Bindi Irwin playbook.


Gosselin and the kids went down to Kissimmee, Florida where, we're told, they hooked up with Boggy Creek Airboat Rides for a private tour.

Sources say the family was taken to a secluded area where Kate threw a birthday bash for the kids complete with pinatas -- and TLC was there to film the whole thing ... naturally.

Talk about upstaging Daddy's birthday party for the kids.
