Edith Bowman and Colin Murray present our weekly show about pregnancy and childbirth. This week, we're at Hay reviewing pregnancy advice books. What kind of pressure is there to have children today, and how does it feel if you either don't want them - or you want them, and can't fall pregnant? Cerys Matthews sings us a lullaby. And in our weekly Bump Club news, the Czech mum expecting quins and the miracle Baby 59 in the Chinese sewage pipe.
