Sarah Rafferty's 2 Children: All About Oona and Iris (2024)

Sarah Rafferty may be known for playing a mom on the show My Life with the Walter Boys, but she’s also a mother off-screen to her children, Oona and Iris.

The Suits alum shares her two kids with husband, Santtu Seppälä, whom she married in 2001. Rafferty and Seppälä's daughter Oona was born in 2007, followed by Iris in 2012.

Thanks to her own family, Rafferty has a special appreciation for playing a maternal figure on TV. “I also am a proud mom in my real life,” she told PEOPLE in December 2023. “My life revolves entirely around my children at this point in my life."

Referencing her character in My Life with the Walter Boys' large family, the actress said, “I’m so grateful for my two. My two are perfect."

It’s not the first time Rafferty has gushed about how much she loves Oona and Iris.

“They are the light of my life,” she told Parents Canada in 2014. “They are so outgoing and funny and silly. They love to sing and dance, they love each other and they are incredibly affectionate. They crack me up every single day.”

Here’s everything to know about Sarah Rafferty’s children, Oona and Iris.

Oona Gray Seppälä, 16

Rafferty and Seppälä welcomed their first child, daughter Oona Gray Seppälä, on Oct. 22, 2007.

On her 13th birthday in 2020, Rafferty celebrated with a sweet photo on Instagram of Oona sitting in front of a birthday cake. “How did that happen? We officially have a teenager. We love her so much we must sing it from the mountaintops. My heart hurts.❤️,” she wrote in the caption.

When Suits was on the air, Rafferty and her family lived a bicoastal lifestyle between Los Angeles and Toronto (where the legal drama was filmed). As a result, Oona grew up going to two different schools.

In a 2013 interview with Redbook, Rafferty revealed that she was “worried” about this set-up but that “it ended up being an amazing, self-esteem-building experience for her. She celebrates it.”

Rafferty has said she is focused on keeping an open and honest relationship with Oona and Iris.

In a 2016 interview with Univision, when Oona was 8 years old, Rafferty explained that she was teaching her elder daughter the importance of “being true to herself and knowing she can talk to us about absolutely anything.”

“I hope that as she grows and moves about in the world independently, she will feel confident because she feels deeply connected to her family,” the Chicago Med star continued. “I hope she feels we can provide a safe space for anything she wants to talk about.”

In the same interview, Rafferty revealed that both Oona and Iris loved coming to the Suits set with her, saying their favorite things to do were visit the craft services truck, the hair and makeup trailer and attend fittings.

“My girls have been dressed up in outrageously gorgeous couture on a few occasions,” she said. “Those wardrobe room photos are treasures for me.”

Iris Friday Seppälä, 12

Rafferty and Seppälä welcomed their second daughter, Iris Friday Seppälä, on Jan. 27, 2012.

The Grey's Anatomy guest star shared that her girls have always been close. “With my 4-year-old, we focus on empathy,” Rafferty told Univision in 2016. “When her sister was crying the other day, we literally got a tissue and wiped away her tears and kissed her. It was so lovely.”

Rafferty may be most well-known for playing Donna on Suits, but her kids aren’t familiar with the show. In a 2024 interview with New Beauty, the actress revealed that her daughters didn’t watch the series, although they were often on set with her in Toronto.

“They were calling ‘action’ and ‘cut’ sometimes and they’re incredibly close to the cast and their families,” she shared.

While her daughters don’t actively watch the USA Network series, Rafferty said that Iris saw a few episodes when she was 11 years old and seemed uncomfortable.

“She was like, ‘I just thought it was weird, Mommy. I just want you to be my mommy,’ ” the former cast member recalled.

The actress added that her daughters had watched My Life with the Walter Boys and liked it more. In fact, Iris was excited for her mom to take on a starring role in the teen Netflix series.

In a 2023 interview with Glamour, Rafferty said that, according to Iris, My Life with the Walter Boys would be the next hit series.

“She crushed The Summer I Turned Pretty, and then crushed [early screeners] of My Life with the Walter Boys [so I’m pretty hopeful]!” Rafferty said.
