Scorsone says her brood is "normal, like every family," explaining that though her middle child Pippa, who was born with Down syndrome, has different needs, Eliza and Lucky "don't disappear." "They're all a part of this constellation of love," says the mother of three, who shares her children with ex Rob Giles. "Pippa and her sisters have a relationship just like any other siblings: sometimes wonderful, sometimes annoying," Scorsone says. "But there is always so much love there." The actress adds that her eldest has risen to the occasion of being a helpful big sister to Pippa and Lucky: "Eliza is very into the idea that she is going to be teaching her sisters a lot of things. She's up for the task."

"Nothing could be better for Eliza's future than having Pippa and Lucky in her life," Scorsone says, adding of her newest addition, "Having Lucky join us has been so wonderful. Pippa loves her baby sister so much and is very protective of her." Opening up about parenting a child with Down syndrome, Scorsone tells PEOPLE that she discovered newfound kindness after welcoming Pippa in 2016. "When Pippa was born, my world and my perspective became infused and alchemized by a deep and unexpected kindness," she says. "No matter how many chromosomes we have, or where we're from, or what we look like, or what gender we identify as, we are all family."
