When Sophie arrives late to school, cold, wet and sad, Miss Blythe helps her share with the class the reason for her sadness. Dad has left home. This is the cue for the class to begin talking about their fathers. They are a varied bunch: one is in hospital, another is in the army; there is a house-dad and a dad who lives with a new family; one child has an adoptive dad, and another has two dads. There are disabled dads and one who has died. Sophie (and we) learn that families are all different. The Milly, Molly books celebrate diversity in all its variety, and this little book, simple and cheerful, will help children understand that each family has its own way of being different.
