Kerry, 30, will have two-year-old Max and four-year-old Heidi live with her in her Surrey home, alongside her other two children, but will have to give Mark 'regular time' with them at his home in Warrington, Cheshire.
Kerry split from cab driver Mark, 39, last year. She was previously married to singer Brian McFadden, with whom she has two daughters, Molly and Lilly-Sue.
Mark and Kerry have agreed to 'work together' to allow Max and Heidi to have a good relationship and quality time with both parents.
What do you think about this? Can these children ever have a stable home-life given all the stories in the media about their mum and dad's breakup?
