Famous Moms and Their Adorable Kids: Happy Mother's Day! (PHOTOS)

Aye-aye, Mason! The eldest Kardashian sister, who’s expecting her second child — a girl — with boyfriend Scott Disick, brings her nattily dressed 2-year-old son to her DASH boutique in SoHo. “Mason is excited [about the baby],” Kourtney dished to Parents magazine. “He came with us to a doctor appointment, and he also loves to touch my belly. We're making this time about him and making sure he feels as if this is his baby. I really don't want him to feel like he'll get less attention once the baby arrives.”
