Ruck and Enos welcomed their first child together, a daughter named Vesper, in 2010. In October 2021, Ruck shared a personal story with The Evening Standard about how he took on the role of "Mr. Mom" shortly after Vesper was born.
"My wife's career rocketed when she got pregnant with our first kid so I was, like, this is my wife's time. I'm Mr Mom," he explained. "When our daughter Vesper was seven weeks old we drove from Los Angeles to Vancouver so Mireille could film 'The Killing.' I'd be in the trailer with the baby and Mireille would shoot a scene, come back busting with milk, feed the baby on one side and pump on the other, give the baby back to me and that's how we did the whole first season. Whoever is the breadwinner in the couple, let them go work."
Vesper has walked the red carpet with her famous parents plenty of times, including the Los Angeles premiere of AMC Network's "Lucky Hank" in March 2023. Enos previously told People, "Vesper is very bright" and "understands emotional ideas beyond her years."
