Kourtney Kardashian certainly knows how to make a splash in Miami!
The mommy of three was a knockout in a sleek white one-piece swimsuit.
The full-coverage suit served her well for her super active day at the pool with her niece, North West!
North seemed to be having a ball while swimming with Kourt.
Most of the Kardashian clan is in Miami filming, and Kim has been keeping busy with photoshoots.
Luckily, Kourtney has plenty of child care experience!
She was also sure to lavish attention on her daughter, Penelope Disick.
Mommyhood does the body good!
