Where You Came From
There's a fun article in The Times in which children explain where babies come from here. I liked this bit: "Mummies have the baby and daddies get to choose the name. There are some differences between boys and girls. Boys have short hair and girls have long hair. Boys are tough and girls are girlie. Boys don't really like princesses. Boys and girls both have nipples. We don't really talk about things like this at school."
