The paranoid-schizoid position is considered the state of mind of children from birth to four or six months of age. Although this position develops into the next position, it is normal to move back and forward between the two positions although some people operate in the paranoid schizoid position for much of the time. As one of the originators of Object Relations theory, Klein sees emotions as always related to other people or objects of emotions. Relations during these first months are not to whole objects but only to part objects, such as the breast, the mother's hands, her face etc.
