SACO — Bring your 3- to 5-year-old preschooler to the library every Tuesday morning for a reading adventure. “Laughing with Lois: Preschool Story-time” involves children’s literature, songs and a craft project, and is designed to help children develop early social and behavioral skills essential for schooling. The program will be held from 10-11 a.m. Tuesdays in the Deering Room of the Dyer Library.
