As a child, your behavior is heavily influenced by your environment, events, and people you are surrounded with. Everything you learn during this time gets embedded into your subconscious mind. 
At an unconscious level, you may take this into your adulthood, as you operate in your daily life from the perspective of the child you once were. This can include feelings of abandonment, childish petulance, rejection, resentment, and self-destructive tendencies from childhood can profoundly impact our relationship with ourselves and others as adults. 
Various techniques such as Hypnotherapy, Emotional Freedom Technique, Reiki Healing, Access Consciousness and Ho’oponopono can be used to address and mend those aspects of you that feel ‘broken’ as we learn to re-discover our connection with our inner-child.
