"I've learned the value of stripping it down to the basics: love, respect, compassion, stillness, to be interested, to be able to absorb the moment. I remember the first time Ripley saw her shadow. My god. It was like shadows had just been invented. It was the most exquisite moment. And it was just dish to me. To actively attempt to be a good mother is basically attempting to be a good person. I never look at my kids and feel that they're mine. I am their caretaker. They own the joint. It's a privilege to be able to take care of them. With my first daughter, I remember waking up and thinking, 'My god, I get to be her mum again today. Wow. It's amazing.' They just take my breath away. All I do is serve themselves back to themselves. My job is just to provide a secure environment where they can just be themselves. It's the cycle that keeps going forward. You give to them, so they can give to their kids. You have to be delighted by that."

"You learn so much. Listen to her. She's in the background. Do you hear that strange noise she makes (like a purr, or a rolled r)? It's the French in her. (Dad is businessman François-Henri Pinault.) It's hilarious. What I learned as a mother is that I have a strong love for things. But the quality of your love gets jaded over the years as you get beat up. What motherhood did to me, when she was born, the amount of love that started pouring out of me was completely pure. Anything anyone ever did to me was erased by this energy. I relearned how to love everything around me, too. My baby is the best thing that has happened to me in my life. It's the most amazing thing."
