Once the embryo takes on the shape of a human, it is called a fetus. In the fetal stage of development, the genes take a back seat to control by environmental information. During this period the fetal body’s structure and function are adjusted in response to the mother’s perception of the environment. Maternal hormones, growth factors and emotional chemistry controlling the mother’s biological response to the environment pass through the placenta and influence the genetics and behavioral programming of the fetus.
I refer to this period where the mother’s perception and interpretation of the world are relayed to the fetus via the chemistry of the mother’s blood as “Nature’s Head-Start Program.” This maternally-relayed “information” about environmental…
