Children have needs at each stage of their development on an emotional, social, intellectual, and physical level.
When these needs are met then children do well and thrive however, when they are not met children will suffer. The degree of what needs did not get adequately met will be the degree of which a part of one self can become stuck or blocked in childhood.
This being stuck means that your beliefs, emotions and behaviors connected to unresolved wounds from your past can get triggered today.
I have found that it works as a wonderful compliment with EMDR and at times Hypnosis.
