This part explores attachment development in children with sensory needs. The guide focuses on what is meant by attachment, development of attachment and how we can support parents and carers of children with sensory needs. This guide is written by Mike Brooks, Chartered Educational Psychologist and the Principal Educational Psychologist for Northamptonshire County Council. He writes here in a personal capacity. This guide is informed by his personal experiences from parenting his son, now aged nineteen, who has profound learning and sensory disabilities, by experience of more than twenty years as an educational psychologist (including roles as a specialist in sensory impairment), and by a range of books and articles on attachment theory and child development.
