On Wednesdays in March, the Blue Hill Public Library will be offering a special 30 minute yoga session during the regular preschool playgroup for kids 5 and under, at 10:30 AM. After the yoga, preschool playgroup will continue as usual until noon. The class, taught by Rebecca Rose Tousignant, introduces children to the practice of yoga through stories, games, songs, and creative movement. The classes are free, thanks to the Friends of the Library. For more information call the Library at 374-5515.
