Sarah Jessica Parker: `I`m a hands-on mum`

The couple have son James Wilkie, eight, and twin two-year-old daughters Loretta and Tabitha. Sarah insisted that they both take full responsibility for raising their kids.

'We don't have any live-in help. We're pretty hands-on parents,' she told Vogue. 'That's something that's important to both of us, and we don't shirk it, because what's the point in having a family if you're not going to really participate in it, you know?'

Her latest movie, I Don't Know How She Does It, sees the 46-year-old play a business woman who balances work and motherhood, but she admitted that she didn't find the balancing act so easy.

'It wasn't hard when I didn't have children,' she said about making Sex And The City. 'I loved it. But I ultimately chose to stop doing the television series because I felt like it required, and deserved, a lot of time when I really wanted to be a parent.'

She welcomed her twins via a surrogate at the age of 44, and said that having children later in life has its benefits.

'I guess I think there are things about it that I hope have made me a better mother,' she said. 'I've had a lot of opportunities to do the things that I wanted to do, like sleep. I have slept till 11:00 for a lot of years.

'Honestly, the only thing that I'm concerned about is the energy. I hope I can maintain the energy.

'I think about all the years I've spent parenting James Wilkie and everything I put into it, and there are two of them.'
