If you've been paying attention to photos of Kourtney Kardashian since she became a new mom, then you'd know that she frequently rotates between the Orbit Infant System and Bugaboo Cameleon stroller. Kourtney spent this past holiday weekend in NYC with her family. It was baby Mason's first trip to Manhattan and with her came the Bugaboo.
Below is a photo from earlier this year of Kourtney pushing Mason in the Orbit during a stay in Miami.

One thing is for sure, well aside from Kourtney's great taste in strollers - Baby Mason will earn some quick frequent flyer miles!
