Where a child repeatedly experiences hostile responses from their primary caregivers, where they are not given the time, space and words to label and talk through their feelings, they consequently communicate their feelings of fear, anxiety, embarrassment and frustration in ways which do them more harm than good.
This is where aggressive and defensive behaviour manifests because the child does not know how to operate from their upstairs, rational brain, and instead operates from their downstairs, reactive brain.
This results in the child failing to thrive emotionally, socially, cognitively and academically. Not just in childhood but with serious implications throughout their life trajectory. Co-regulating these uncomfortable and overwhelming emotions from the beginning, can give the child a healthy and robust foundation from which to navigate their way through life.
