Being a teenage model was lot of fun, like playing dress-up. I'd feel ugly and awkward and chubby, and they'd transform me. Not that that makes everything better. Then my mom shopped the pictures around, I guess, and the agencies started calling. I wound up going with a little agency, Spectrum. It all happened really quickly, I started modeling for magazines like YM and Seventeen, and I did a couple of bigger things like Italian Vogue.

We put so much pressure on ourselves as parents to be able to do everything, but children are very grateful and understanding. I always find that quality time, even if you just get a little bit, really has a deep impact. But you also need them to know that they can make mistakes, and if they do make a mistake it's OK for them to tell you and that they'll get a second chance.

Getting pregnant and caring for a baby gave me a confidence I'd never had before. I really felt I'd done something well, and I can't say that about anything else in my life. I've never watched a movie I've appeared in and thought, wow, I was great. I always think, oh, I could have done this better.

I've seen beautiful and profound change and growth in men who are becoming fathers. Women get to carry the baby, so you might get a little head start on them, but watching a man get to know the little person, seeing that bond evolve and seeing the difference in the relationship between fathers and their sons and daughters, is fascinating.

My mom has a diary entry or something where I wrote, "I think Steven Tyler is my father." I had the same feelings for Todd Rundgren, who raised me as his daughter. I would go to sleep at night and wake up at like 6 in the morning and creep up the little steps to the tower where he would be on his computer. I would just sit there.

There are many important elements to being a parent. A lot of people don't have fathers but they might have someone in their life who's a good male influence and support. There's no cookie-cutter way of raising children and no family is the same, but the most important thing is that children are loved, supported and cared for, whether it's coming from a relative or a friend or a grandfather or a good school teacher. Anyone. Children just need good examples and mentoring to teach them and show them how to do things.

Beauty is not defined by the size of your jeans.
