Who is Terrible in the Terrible Two's

I have often heard of the phrase "The Terrible Two's", well I wonder what this is and to whom the word "terrible" is associated to. On the surface I understand it to be a nasty time during the developmental of a child. Well I have stopped now to wonder if a child can actually be "nasty" when the child is about two years of age. What is this age and what makes the child terrible?. Well observing my own child I think this is time when the child has passed the age of full development of his senses i.e vision, hearing, touch, taste and smell. What has developed in these in neurological terms is actually the pathways to the brain from the sense organs. what we need to notice is that the brain is still in the stage or development and would be in development for the rest of the child's life into its adult development.

Well how can we make sense of this "terrible two"? Let me take two perspectives one from an adult or the so called parent position and the other the child position. First let me state that it is quite obvious that the adult such as you and me are in a different plane, which means that we have passed that age and now gone into a higher place, which means that it naturally places us in a position to pass a judgment about some one in the lower plane. Our judgment "we think" arises from our expertise. What are we expecting from a child. We expect "discipline" and why do we need to this, so that the child can fit into our society and function well in our society. We expect our child to develop certain behavior that will help him/ her to be good to people around

If we ever did understand what their world is then one would never have found or invented the phrase :"The terrible two's"
