Kourtney Kardashian Has Baby Boy Mason Dash Disick.  Kourtney welcomed a healthy baby boy into the family named Mason Dash Disick, who came in weighing 7 lbs., 6 oz., and 19.5 inches. The off again, on again couple Kourtney and Disick are happy to welcome the newcomer and were very excited to have a baby. Kourtney said back in October, "A boy is definitely needed in this family! Scott and I are thrilled to add a little boy to the bunch." If you're wondering where the name Dash came from it's simply the Kardashians' clothing boutique name! Congrats to the couple and we're glad Kourtney had a safe and healthy delivery.
