Another busy day for Kourtney Kardashian.

The Keeping Up With the Kardashians star, 37, stepped out with son Mason, 6, on Tuesday (August 16). Before her workout, the single mom took her son to an art class in Woodland Hills, Calif.

Later that day, the reality star posted a photo with son Reign, 20 months, via Instagram.

“While we try to teach our children all about life, our children teach us what life is all about,” she wrote.

On Sunday, we spotted Kourtney and her three children — including 4-year-old daughter Penelope — at church in L.A.

While we try to teach our children all about life, our children teach us what life is all about.
