Writers need to be careful about putting their children in memoir or in fiction. We're their custodians.
I've been asked this question so often I've begun to assume that the world is teeming with aspiring writers wondering what Thanksgiving dinner will be like after they publish that lightly fictionalized exposé of Mom's actionable parenting skills and Dad's affair with the babysitter. When asked, I usually reply: "Write what you want. People rarely recognize themselves on the page. And if they do, they're often flattered that a writer has paid attention."
