Public libraries across the nation continue to transform themselves into learning centers for infants, toddlers, and preschoolers. There are many resources available to help librarians create baby-friendly play spaces and enhanced storytimes, but until now there has been gap in the literature addressing the developmental needs and changing behaviors of babies and toddlers. Parents and caregivers can also present unique service challenges. Focusing squarely on the how of providing quality library service to babies and families, Knoll’s new book provides sensible, sensitive advice on meeting their physical, emotional, intellectual, and social needs. Geared towards helping public libraries foster healthy growth and development for their littlest patrons, this book: explores multiple aspects in the developing life of a baby, discussing physical needs, emotional expressions, intellectual pursuits, and social development; highlights real-life examples from public libraries that relate to how these developmental processes present themselves while babies and families interact in the library; presents Baby Steps for each topical area, providing service tips and suggestions that can be easily or inexpensively put into practice; offers Big Steps, conversational points that invite librarians to think creatively about further investment, support, funding, and collaborative efforts; and includes carefully selected research findings and other information that can be used for planning, policymaking, and advocacy. With Knoll’s guidance, children‘s librarians will be informed and inspired to rise to the challenge of providing quality service to babies, toddlers, and care providers.
