A working livery school in Norton is home to six Shetland ponies being trained as therapy ponies to help children and vulnerable adults. Smile at Lightwood is an initiative of the Lightwood Livery at Mansion House Farm, Norton. Six miniature Shetland ponies came to live at the farm in late 2014 and have since been training for careers in pony parties and as therapy ponies helping young people, the elderly and vulnerable adults, at the farm and in the local community.
