Sophie: I then had to learn to settle down. That's an awful dreary phase. The first person I ever learned to settle down or commit to was my own child. I suppose the book is the story of what happens. Everyone talks about growing up and calming down and settling down and then doing the kid thing. I had the kid and then had to work out, how the hell do I do the rest of it? Do I need to? What is calming down? Do you have to settle down? Why does a mother who has a child have to stop going to parties or stop going on dates? Can you commit to your child but also have that exciting private life? I think my book is an exploration of how that went.
