Hilary Duff and Her Sweet Son Are Instagram's Cutest Duo

You watched Hilary Duff grow up before your eyes on Disney Channel's Lizzie McGuire, and now the proud mom is sharing her adorable son's childhood on Instagram. When Hilary isn't busy filming her show Younger, the multitalented 30-year-old devotes her time to her adorable son, Luca.

Hilary and her ex-husband Mike Comrie welcomed Luca in March 2012, after which she shared sweet baby pictures with the world. "He's taught me so much," she told POPSUGAR about her 6-year-old back in May. "I feel like I was never this patient, but [being a mom has] made me a nicer person, and I apply it to other aspects of my life." And Hilary's mommy moments are only going to get cuter from here. She is currently expecting a baby girl with her boyfriend, Matthew Koma. Read on to see Hilary's best family pictures ahead.
