Attachment parenting, a phrase coined by pediatrician William Sears, is a parenting philosophy based on the principles of the attachment theory in developmental psychology. According to attachment theory, the child forms a strong emotional bond with caregivers during childhood with lifelong consequences. Sensitive and emotionally available parenting helps the child to form a secure attachment style which fosters a child's socio-emotional development and well being. Less sensitive and emotionally available parenting or neglect of the child's needs may result in insecure forms of attachment style, which is a risk factor for many mental health problems. In extreme and rare conditions the child may not form an attachment at all and may suffer from reactive attachment disorder as defined in DSM-IV and ICD-10. Principles of attachment parenting aim to increase development of child's secure attachment and decrease insecure attachment. Although there is research which shows that when mothers are taught to increase their sensitivity to an infant's needs and signals.
