Hudson has 11-year-old son Ryder with ex-husband Chris Robinson and Bingham, four, with Belamy.
Although Belamy and Hudson are no longer romantically involved, they have remained on good terms for the sake of their family unit.
Hudson claims the change in living arrangements has been easy for everyone to adjust to.
"We said, 'We need to try to create something for the kids where they feel like they're gaining something rather than losing something."
"It's been a seamless transition. Kids just want to see their parents be cool. Everybody's cool; everybody's good.
"We create the experiences that we want to have. If you want to create the painful experience, you can do that.
"You have the power to make (any) situation a painful or a difficult one. I want to try to create experiences that will be positive for my kids."
The 36-year-old actress wants her children to have an encouraging male role model in their lives, and she realises the importance of this since she has such a close relationship with her stepfather Kurt Russell, the long-term partner of her mother Goldie Hawn.
"Being someone who has come from a broken family and has a stepfather, I really benefited from having that very consistent (presence) in my life," she added.
"And it's something I am mindful of and want in my life."
