Scorsone, known for portraying Amelia Shepard on Grey’s Anatomy, married Giles, a musician, in 2009. The pair share three daughters: 7-year-old Eliza, 3-year-old Paloma “Pippa” Michaela, and Arwen, who was born in December.
The actress announced the arrival of their baby girl with a photo of big sister Eliza cuddling with the newborn.
“Arwen is here! Our family wishes you a happy new year, a happy new decade and a happy heart made new by love in every exquisite moment,” Scorsone captioned her Instagram post.
In April, the Grey’s Anatomy star revealed that she and Giles decided that Arwen would go by her middle name: “Lucinda, ‘Lucky’ for short,” per the caption of a photo she shared of herself cradling Arwen while curled up in an armchair at home.
In the past, Scorsone has been open about raising her girls and how her perception of parenthood has shifted over time, especially after she learned that Pippa had been diagnosed with Down syndrome.
“What I unconsciously thought about my job as a mother was that I was supposed to equip her to survive in a competitive world,” she said on the Motherly podcast last March, revealing that she was initially sent “into a tailspin” when she realized that Pippa “was going to have some physical differences and some cognitive differences.”
But then one day, “This simple voice came to me where I was like, ‘I don’t know what to do — oh, I’m supposed to keep her safe and I’m supposed to make her feel loved,'” Scorsone said. “And suddenly my understanding of my job as a mother completely distilled and opened.”
