These attachment patterns are broken down into Avoidant or Ambivalent attachments. Children who show these insecure attachment patterns have learned that there are conditions attached to their gaining proximity to their mother.
Interestingly these children develop appropriate strategies that a) increase the mother’s emotional availability and do not cause her to withdraw and b) bring care and protection. These strategies are of course devised for survival and can be effective, but the feelings of anxiety and insecurity remain in relation to the mother.
However both secure and insecure attachment patterns represent efforts by children to ORGANISE their behaviour, to achieve some kind of proximity to their mother and with it a “felt security” – and when there is an insecure attachment pattern, these behaviours in children have varying degrees of success. https://childprotectionresource.online/category/attachment-theory-2/
