From the publisher: "The first year of life is a critical time for infants to begin developing secure attachments with their parents and caregivers (secure attachment is when children know they can depend on adults to respond sensitively to their needs). This helps babies learn that their world is a safe place and it is an important foundation for self-regulation development. When babies transition to childcare outside of the home, they need to form relationships with other caregivers and learn through experience that their needs will be met."
