Mason Disick monkeys around in Malibu with the help of mom Kourtney Kardashian and his Aunty Kim.

The adorable threesome were living the park life over the weekend…sliding, climbing and just hanging out.

Kourtney, who looks like she’s about to pop, has no problem playing around with her boy while awaiting the arrival of her second child.

Cutest three amigos we’ve ever seen!
