Heather Cook knows being a mother comes with all sorts of challenges. Inspired by her own experiences, Cook hopes to lighten the load for young mothers with her new book, “You’re Welcome, Mama.” Described as a lighthearted read for overwhelmed moms, the book will be released on Nov. 13, also known as World Kindness Day. What’s Cook’s background? Born and raised in Elizabethton, Cook has always lived in the Tri-Cities area.
