No one can stop baby Louise crying - not mum or dad or grandma or grandpa, not even the neighbours. Her crying shakes the pictures from the walls and wakes all the neighbourhood cats and dogs. But when Daniel arrives home from school, he just says 'Oonga boonga' to her and she stops crying and smiles. However, when Daniel goes out to play, the crying begins again, and mum and dad saying 'Oonga boonga' doesn't help at all. It is only when Daniel returns and whispers 'Bunka wunka' that the magic works again. A happy story emphasizing big brother's influence and how important he is to his baby sister. Special illustrations.
