Kourtney Kardashian (“Keeping up with the Kardashians”) is one POSH Mommy and isn’t afraid to the tell world how she was able to loss 30 pounds after giving birth to cutie pie baby Mason Dash.

Kourtney was recently seen in Miami – who’s in town filming the second season of  E!’s Kourtney & Khloé Take Miami – to debut her  limited-edition design for Belly Bandit ($66).

This POSH mom credits the belly wrap by stating how quickly it helped her get back into bikini shape. “My doctor told me not to workout at all until 6 weeks after giving birth so the belly bandit definitely gave me a jump-start on my weight loss. I wore it [belly bandit] consistently for 45 days. I brought it with me to the hospital and put it on right away. It even helps me with my posture. It is truly the miracle accessory I cannot live without!

While promoting her belly band, Kourtney was also on hand to help author Amy Tara Koch celebrate the launch of her maternity fashion guide, Bump It Up, at the W South Beach Hotel in Miami, FL on April 1.
