The star and his wife Rebecca Romijn dote on their girls Dolly and Charlie, who were born in 2008 - but Connell admits it's "not easy" looking after them now they've hit the 'terrible twos'.
He tells Britain's OK! TV, "My wife and I switch (child care duties) - one of us has to be home with them. It's easier to work than it is to be home with them - that's a real job. I'm relaxed when I'm at work!
"It's funny, everyone calls them the terrible twos - in our household it's like the 'I dont know how we're gonna do this' twos. They're adorable but it's not easy."
