Shirley Ward in her book Healing Birth, Healing Earth draws on her own experience as a therapist and many strands of research to stress how inclusion and boundaries are experienced prior to birth, and it makes sense that a baby in the womb can be creative!
And when we are little children we pick up on inclusiveness, creativity, and boundedness very quickly, getting strong messages even before we are able to talk.
We learn very quickly that a frown or some indication of disapproval, from our parent (or another principal carer as we get a little older) indicates a boundary. A smile, however, or a warm touch, informs us that we are included. We then learn that we can, in turn, influence our environment and those around us with our facial expressions, body posture and movement. (This two-way knowledge flow is vital for our development and is why I included affect as a root foundation earlier).
In our good enough family, as we grow older, we will be allowed explore the physical world around us and we will notice that we can influence that world, i.e. create. The natural curiosity that all children have enhances creativity as we grow older.
We learn boundaries as we have to get up to go to school, do our homework etc. As we grow, healthy development will almost always involve us having friends, or feeling included. Our parents, teachers and other people in authority teach us necessary boundaries. The healthy adult has a workable balance between all three elements.
In most of us one of them will be dominant – but they are all there at different times if we are willing to look for them.
