Sarah Jessica Parker says children can "distract" from a relationship.
The 'New Year's Eve' actress - who has three kids, James, nine, and two-year-old twins, Marion and Tabitha, with husband Matthew Broderick - admits marriages can suffer once a child comes along and it's important to make time for each other.
She said:'Kids can really distract you from your relationship. Maybe in good ways and bad ways. It's important to have all eyes on all parts of the relationship.
"It's something you really have to pay attention to. But you figure it out."
Sarah and Matthew have been together for 20 years and the 'Sex and the City' star admits they've had their ups and downs.
She told Stella magazine: "He does lots in the house. He shops for me a lot and he cooks for all of us. There are a lot of things he does better than I do, so it balances itself out. I don't feel taken advantage of. We take care of each other.
"We've been together for 20 years and you have good days, you have decent days, and you have bad days. That's a marriage. That's a relationship. That's a friendship, even - relationships outside the marriage run the same course. If you're in it f or the long haul and you want meaningful relationships you are going to go through lots of different periods."
