If a mother is extremely anxious (about her pregnancy, her abilities as a mother, or any other problems in her life), the unborn child may be affected. Although the baby's nervous system is separate from the mother's, strong emotions in the mother such as rage, fear, and anxiety cause a great increase of hormones and other chemicals in her bloodstream. These substances pass through the placenta wall, and it is believed that they can reproduce the mother's physiological state in the fetus.
