Following the thread about where the desire to have a family of a particular size comes from, I've been thinking about the depiction of families in children's books. Of course, most families have more than one child and it's not surprising that children's books reflect this. A few that come to mind from my youth are
Narnia Chronicles 4
The Railway Children 3
Ballet Shoes 3
My Family and Other Animals 4
BabyBocca is a voracious reader and I'd like to find her a book which depicts an only child (and ideally as part of an ordinary family set-up, rather than (say) an orphan). Milly Molly Mandy is the only one I can think of but surely there are others.
Any suggestions?
