The mom-of-three posted a number of Instagrams to commemorate the day, including one colorful snap where she's giving her 3-year-old daughter, Penelope, a piggyback ride.
"Murakami piggy back ride," she captioned the photo.
In another post, Kourtney shared a photo with her 6-year-old son, Mason, inside Yayoi Kusama's Infinity Mirrored Room, a dark room that's been lit up with tiny lights and has been featured on many Instagram feeds as of late.
Just 12 hours before the museum trip, Kourtney gave new meaning to the term "mom bod"in a mirrored room of her own. She shared a sexy mirror pic, donning just a black body suit and chocker, on Instagram.
"Sometimes good morning means goodnight," she captioned the photo.
The 36-year-old reality star is known for taking her three kids -- Mason, Penelope and 1-year-old son, Reign, whom she shares with her ex-boyfriend, Scott Disick -- on really fun day trips.

While Kourtney's focus appears to be on her children, their father has been travelling all over the place. Watch the video people to find out what Scott has been up to lately.
