Kate Hudson "threw every kind of parenting manual out of the window" when she became a mother.
The 'Bride Wars' star - who has 13-year-old son Ryder and Bingham, six, from previous relationships - admits it has been tough raising her kids as a single mother.
She said: "As a single mum of two you have to work pretty hard. The logistics of where we film can be challenging when you're raising children. Parenting shifts as your kids shift. The best thing for me has been throwing any kind of parenting manual out of the window. It's a very different relationship when your kids become teenagers. Ryder's 13 now - how I raise him is very different from Bing, who's 6, because they're very different personalities."
And the 38-year-old actress has praised her mother Goldie Hawn and stepfather Kurt Russell for always wanting the best for her and her siblings.
She added: "My parents wanted us to be the best we could be. But it was never an expectation we felt that we couldn't reach. My mum put me in dance class when I was really young and I went four or five times a week. When you're young and you have that discipline, you feel connected to being active. I'm fascinated by what makes people feel happy. It's something that my mum and I are very in tune to. What being active does for our brain is truly one of the most beneficial things we can do to promote happiness."
And Kate hasn't ruled out having more children in the future.
She told The Times magazine: "I love being really busy. I'd like to do a triathlon - that's a bucket-lister. I want to have more kids. But I'm starting to think about what really makes me happy. I've worked solidly since right out of high school and I have this worker mentality. I don't think I could ever not work. I'll always figure something out."
