With all three of her children born on “Keeping Up With the Kardashians,” Kourtney Kardashian is the resident mother of the Kardashian clan. As she’s constantly reminded us, she takes that role seriously. Her youngest son Reign Aston was born on December 14, and the new mom is still breastfeeding. US Weekly reports that Kourt Instagrammed the picture below after a night of party-hosting duties at the Marquee Dayclub at The Cosmopolitan, Las Vegas: 

After the show it’s the after party.

The photo comes after Kourtney shared a few more typically Vegas party pictures of herself and a group of friends preparing for a day of poolside clubbing. Her caption for the pump picture? “After the show it’s the after party.” As Kourtney reminds us, Moms can party AND pump.

This reminds us of another new mom – Kourtney’s sister Kim Kardashian. When Kim “broke the internet” with her naked body, she got plenty of love and an endless stream of backlash. But some were even more offended by fellow mom-leberty Alyssa Milano’s breastfeeding selfie. This Instagram is the combination of both. Kourtney is everything we love about the Kardashians here: she’s Vegas and family, paid to party and still getting press off of pumping. Get it, Kourtney and get it, moms.
