The decision not to have children is often portrayed as a selfish one. Former prime minister Julia Gillard was criticised for being childless and Brisbane woman Tanya Williams also decided a long time ago that having children wasn't something in her life plan. But she says admitting that her decision not to have children was one of choice meant being judged harshly and unfairly. Tanya has written a book about her decision and her experiences. The book is called A Childfree Happily Ever After and Tanya is chatting with Loretta Ryan.
