                                                                The Child Ego State

     The Child ego state is a set of behaviors, thoughts and feelings which are replayed from our own childhood. 

     Perhaps the boss calls us into his or her office, we may immediately get a churning in our stomach and

wonder what we have done wrong. If this were explored we might remember the time the head teacher called

us in to tell us off. Of course, not everything in the Child ego state is negative. We might go into someone's

house and smell a lovely smell and remember our grandmother's house when we were little, and all the same

warm feelings we had at six years of age may come flooding back.

     The Child ego states are constantly being updated. For example, we may meet someone who gives us the

permission we needed as a child, and did not get, to be fun and joyous. We may well use that person in our

imagination when we are stressed to resist our old ways of thinking that we must work longer and longer hours

to keep up with everything. We might ask ourselves "I wonder what X would say now." Then on heating the

new permissions to relax and take some time out, do just that and then return to the work renewed and ready

for the challenge. Afterwards, rather than blaming ourselves for what we did or did not do, what tends to

happen is that we automatically start to give ourselves new permissions and take care of ourselves.

     Alternatively, we might have had an extremely unpleasant experience yesterday which goes into the Child

ego state as an antique memory that stands in the way of our growth Positive experiences will also go into the

Child ego state as antique memories. The positive experiences can then be drawn on to remind us that positive

things do happen.

     The process of analyzing personality in terms of ego states is called structural analysis. It is important to

remember that ego states do not have an existence of their own. They are concepts to enable understanding.

Therefore it is important to say "I want some fun" rather than "My Child wants some fun." We may be in our

Child ego state when we say this, but saying "I" reminds us to take responsibility for our actions.
