Inner child work, also referred to as inner child healing, is a way to address our needs that haven't been met as children and heal the attachment wounds we've developed. We all have a younger part of ourselves that was never quite loved the right way or the way they needed as a child.
Inner child work, like any type of inner work, involves creating a space where your subconscious is allowed to take the lead. Inner work is the act of going inside ourselves, to explore our true feelings and parts of us that may have been rejected and labeled as "inappropriate" or "too much" by others. By allowing ourselves time to go within, we begin peeling back our everyday coping mechanisms (being avoidant, numbing of our feelings, etc.) and are able to fully accept and integrate our subconscious into consciousness.
