Kourtney Kardashian, Penelope and North West Hit up Central Park Ice Rink

Kourtney Kardashian was holding on to her dear life in NYC ... her dear life named Penelope.

Kourtney's mommy & me day with Penelope in Central Park Sunday also included North West. They skated to "Redbone" by Childish Gambino and then took a walk under some light rain. It was quite the escape from L.A. where it was a steamy 81 degrees.

Kourtney's really getting the hang of this ice skating thing. But more than that, she's totally nailing the part of kool mommy and fun auntie.
