All parents recognise nits as a disgusting fact of life.
Whether we like it or not, sooner or later all children get infected and come home scratching, with a cargo of unwanted stowaways. The nurse and her napalm may have gone but the head lice are far from absent. No longer threatened by such a formidable enemy, nits are now baby booming on scalps across the land. They recognise no social barriers and are just at home in Eton as in the inner city. Our local school in Wales is no exception, suffering regular outbreaks during the three years that our son, Jack, has attended.
