As you drive or walk by yard, garage, or sidewalk sales, be on the lookout for tables of children’s books. Many people empty their shelves of toys and books as their children outgrow them. Buying secondhand books can be an inexpensive way to build your child’s library.
On the flip side, if you have books that your children have outgrown or you want to pass along, give them to friends, libraries, hospitals, schools, day care centers, and so on. Share those books!
