“If a child is born totally blind, how will that limitation affect her connection with those around her? The literature estimates that 75%of most people’s learning comes through vision (Smith & Cote, 1982). A deaf infant with normal vision will not have the same trouble developing early bonds with his caregivers as an infant who is blind because, as we have seen,the eyes are a main avenue for these early bonds.”
