Can you change your attachment style and if so how?
Yes, you can. But, there are many important considerations to keep in mind.
Attachment conditioning dictates much of how we behave in relationships, view ourselves, how well we explore our world, and how good we are at emotional self regulation (Brown et al., 2016). This conditioning is largely determined very early on between the ages of six and twenty-four months (and to a lesser degree up to three years). The conditioning that takes place at this time occurs at the procedural or implicit level, which is pre-verbal.
