RELATED: Caterina Scorsone Opens Up About Raising a Child Who Has Down Syndrome: 'My Daughter Is Perfect'

Earlier this year, Scorsone opened up to PEOPLE about raising Pippa, who was born with Down syndrome, saying her "difference lit a match in my life and in the life of my family."

"When my daughter Pippa was born, I was scared. I didn't know anything about trisomy 21, the name for the occurrence of a third copy of the 21st chromosome, better known as Down syndrome," she said. "... I didn't know anything. All I knew about Down syndrome was that people were afraid of it, so I figured I should be too."

The star, who also shares daughter Lucky, 17 months, and Eliza, 8, with ex Rob Giles, explained how she quickly shifted her perspective, seeing any of Pippa's differences as beautiful individuality like anyone else's unique attributes. Scorsone said Pippa's arrival "cracked open a door in my life" — for the better.

"It suddenly became crystal clear," she said, adding, "There is no standard, objective, perfect human being. The metrics of perfection are arbitrary and imposed in the service of those who fit them. My daughter is perfect. Exactly the way she is."

"Pippa is perfect exactly as she is. So are you, and so am I. The only way we lose sight of that perfection is to look for it somewhere else," she said.

Scorsone said her life has been infused with kindness ever since Pippa was born — and since she connected with other families with differently abled children.

"I didn't really know what family could feel like until I entered the disability community and met other families that loved and included a person with Down syndrome," she said. "These hilarious, real humans reached their arms around us when Pippa was born and pulled us into the most joyful, fierce hug we've ever experienced."

Reflecting on what she now knows that she didn't prior to welcoming Pippa, Scorsone said "the birth of a baby with Down syndrome is something to be celebrated rather than feared."
