A toddler who is securely attached to his or her parent (or other familiar caregiver) will explore freely while the caregiver is present, typically engages with strangers, is often visibly upset when the caregiver departs, and is generally happy to see the caregiver return. The extent of exploration and of distress are affected, however, by the child's temperamental make-up and by situational factors as well as by attachment status. A child's attachment is largely influenced by their primary caregiver's sensitivity to their needs. Parents who consistently (or almost always) respond to their child's needs will create securely attached children. Such children are certain that their parents will be responsive to their needs and communications. 
There is a consensus that the most effective interventions for enhancing attachment security are those targeting parental sensitivity through video-feedback. Through this procedure, parents become increasingly aware of their interactional style and the needs of their children. For best results, these interventions should be of short duration (., fewer than 5 sessions) and implemented when the child is 6 months or older. Nevertheless, interventions should not only focus on increasing parental sensitivity but also on decreasing or eliminating atypical caregiver behaviours. An exclusive focus on parental sensitivity may neither be sufficient nor effective in preventing disorganized attachment. As such, sustained and intensive home-based interventions are recommended to reduce disorganized attachment. Regular weekly follow-up to promote the maintenance of what has been learned by parents should also be considered.
