Tiff, Taff, and Lulu — Eva Montanari

Tiff, Taff, and Lulu are sisters. Their mummy always tries her best to be fair when the girls are taking a bath or having their teeth brushed, but because there are three of them, someone is always first and someone must always be last.
When an argument on a scooter leads to a three-wheeled mishap with Mummy, Tiff, Taff, and Lulu finally realize that some things are more important than being first.
