Kim doewn't want to have swimming lessons at school because of her eczema. She finds the red patches embarrassing. Her mum takes her to see Dr Toby, who explains all about eczema in simple terms. He gives Kim a prescription for a strong ointment (presumably a steroid cream) to use for a few weeks, to be followed by a milder one. She also is to use bath oil. Soon the eczema is better, and Kim is proud to show Dr Toby her new bathing costume. An occasional Australian term might need explanation.
