Your two year old is building an understanding of herself as an individual, which increases her confidence in interacting with people, objects, and experiences in the world around her. Healthy social and emotional development begins with your child having an attachment to other human beings. It is important that your two year old feels loved, important, and worthy. Because of that bond with you, she trusts that the world is a good place. These early relationships form the basis for all other relationships and interactions that she will have.
