The document discusses the prenatal development period from conception to birth. It is divided into three trimesters and important organs are formed. Hazards during this period like malnutrition, smoking, drinking and stress can negatively impact the fetus's development and lead to physical and psychological problems that persist after birth. Irregularities during prenatal development are often the root cause of psychological issues individuals face as adults. The prenatal period is very important as a child's future behavior is determined during this time.
