In September, Katie will be starting school. The school have a rather well worked out induction period involving visits first with a parent and then without, and the filling out of a booklet about her likes, dislikes, attributes, and abilities, including some questions about basic knowledge such as ability to name shapes, colours, and body parts.
"Katie," I told her, "your new school wants to know if you know any bits of the body. Can you think of any?"
She thought about this carefully.
"Skeleton?" she suggested.
Give her time; by the end of primary school I expect I'll have her up to scratch on the full list of internal organs.
