The `I Don`t Know How She Does It` actress - who has children James, eight and twins Tabitha and Marion, two, with husband Matthew Broderick - would happily give up her career if it meant she could go on an "adventure" with those closest to her.
She said: "I often have a fantasy about packing up the family and travelling. If it was an adventure, sure, I`d leave all this behind.
But I`d never do it without them."
Despite her successful career, 46-year-old SarahJessica admits she is not any easier on herself as she has gotten older because having children means life can be tougher.
She said: "Having children makes it harder now. When you involve other people who are reliant on you, the stakes are monumentally higher. I don`t mean to be dramatic, it`s also beautiful and filled with meaning."
However, she is happier she waited until she was older to expand her family as it meant she really enjoyed her career.
She added to Style magazine: "Am I glad I waited? Yes. Most assuredly, because there were lots of things I wouldn`t have done had I had children at the time. I could work 18 hours a day and love it and maybe act in a way I wouldn-t act now."
