Reese Witherspoon has taken a step back from acting to make her family her number one priority.

Reese - whose last film 'Hot Pursuit' with Sofia Vergara came out in May - said: "My family comes first. I haven't made a movie probably in a year and a half. I'm focused on my business, but also I want to spend time with my teenage daughter. It's terrifying that my oldest child is about to leave [home to go to university]. I can't imagine not sitting at the foot of her bed, saying, 'So what happened at school today?' "

The 39-year-old actress accepts "it's hard" to raise well-rounded children in Hollywood and she is particularly strict about what they watch on TV.

Speaking in Glamour magazine, she said: "You hope you're saying the right things - but also, as a kid becomes a teenager, you feel like there's a ticking clock to tell them everything they need to know. My kids make me laugh every day. And they're so supportive. As I get older, they understand things I worried about - the guilt of being gone - in a way that's so healing for me, when they say, 'Mom, we know you love what you do. We love to watch you do what you do.' "

Reese and Jim have been happily married for four-and-a-half years and she insists nothing has "wildly changed" between them since they first began their romance.

She said: "I just love him more and more. I want so much for him to be happy, and he wants me to be happy."
