““Even without world wars, revolutions and emigration, siblings growing up in the same home almost never share the same environment. More accurately, brothers and sisters share some environments — usually the less important ones — but they rarely share the one single environment that has the most powerful impact on personality formation. They may live in the same house, eat the same kinds of food, partake in many of the same activities. These are environments of secondary importance. Of all environments, the one that most profoundly shapes the human personality is the invisible one: the emotional atmosphere in which the child lives during the critical early years of brain development. The invisible environment has little to do with parenting philosophies or parenting style. It is a matter of intangibles, foremost among them being the parents’ relationship with each other and their emotional balance as individuals. These, too, can vary significantly from the birth of one child to the arrival of another. Psychological tension in the parents’ lives during the child’s infancy is, I am convinced, a major and universal influence on the subsequent emergence of ADD. A hidden factor of great importance is a parent’s unconscious attitude toward a child: what, or whom, on the deepest level, the child represents for the parents; the degree to which the parents see themselves in the child; the needs parents may have that they subliminally hope the child will meet. For the infant there exists no abstract, “out-there” reality. The emotional milieu with which we surround the child is the world as he experiences it. In the words of the child psychiatrist and researcher Margaret Mahler, for the newborn, the parent is “the principal representative of the world.” To the infant and toddler, the world reveals itself in the image of the parent: in eye contact, intensity of glance, body language, tone of voice and, above all, in the day-today joy or emotional fatigue exhibited in the presence of the child. Whatever a parent’s intention, these are the means by which the child receives his or her most formative communications. Although they will be of paramount importance for development of the child’s personality, these subtle and often unconscious influences will be missed on psychological questionnaires or observations of parents in clinical settings. There is no way to measure a softening or an edge of anxiety in the voice, the warmth of a smile or the depth of furrows on a brow. We have no instruments to gauge the tension in a father’s body as he holds his infant or to record whether a mother’s gaze is clouded by worry or clear with calm anticipation. It may be said that no two children have exactly the same parents, in that the parenting they each receive may vary in highly significant ways. Whatever the hopes, wishes or intentions of the parent, the child does not experience the parent directly: the child experiences the parenting. I have known two siblings to disagree vehemently about their father’s personality during their childhood. Neither has to be wrong if we understand that they did not receive the same fathering, which is what formed their experience of the father. I have even seen subtly but significantly different mothering given to a pair of identical twins.””
