Kim, Kylie and Kourtney Get Outta Costa Rica with Sickeningly Cute Kids

Kim KardashianKylie Jenner and Kourtney Kardashian had to haul extra luggage to the airport ... and appeared to handle it all on their own.

Kim had 2 handfuls with North and Saint, Kourtney lugged Reign ... and even Kylie was on (step)mom duty with Tyga's son, King Cairo. The fam was loading up for the return flight from Costa Rica. Looks like Khloe and Kris dodged kiddie duties.

There's no debating how adorable the kids are, but Kim's choice in footwear?

Check out the pics ... probably not the wisest with 2 tots on board.
