Resilient or Adaptable?

When we look at an infant or a child, we see a human being who, through every experience, is constantly changing, growing neuron connections, developing beliefs about himself and life, adopting "programming" on how to behave, what to expect and how to react. Often people talk about resilience, and how children can so easily bounce back from setbacks. The definition of Resilience refers to our ability to return to a pre-stressor state. But is that actually possible for a child? If his brain is developing and forming neuron networks at an ever-increasing rate as he interacts with his environment and the adults in it, and developing an understanding of "his" world, how could he ever go back to pre-stressor state? Not having developed all of the higher level "thinking brain " functions yet, which would allow him to rationalise stressful events and maybe even grow stronger from them, Adaptability I believe better describes the child's nature: he possesses an astounding ability to change, particularly in relation to stressful circumstances, but can never go back to his original state. In light of this I strongly recommend to intentionally provide a healthy psychological, physical and emotional environment for our child, as it will greatly contribute to the formation of a balanced and strong character.
