Every Saturday Steven watches his sister at her ballet class - jumping and dancing - and he longs to join in. But his mother says that real boys don't dance; they play games like basketball.

Michelle Magorian says her inspiration for Jump! came from the comments people used to make about her eldest son when he was still in nappies, saying "I was surprised to hear people talking about all the "boyish" activities he would take part in when he was older and thought, 'What if my son preferred dance to rugby?"'
