It was a family-filled day for Kim Kardashian yesterday. On Sunday afternoon, the reality starlet spent some quality time with her expecting sister Kourtney, as well as the littlest member of the Kardashian clan (for now), Mason.

After dropping some dough on designer duds at Madison, Kim and Kourtney took Mason to play at a park nearby. While Kourt took a bit of a breather, Aunt Kim was on Mason-watch.

Now that ALL the Kardashians are back in LA, I’m sure that the entire family is gearing up for what should be a very exciting summer!
