Prenatal development of a child represents a process that begins with the fertilization of an egg by a sperm and continues until birth. During this period, the child undergoes incredible changes, starting from a single cell to a fully developed organism capable of independent life. The first part of pregnancy marks the beginning of development, where after conception, the egg divides and forms a blastocyst. The implantation of the blastocyst into the uterus establishes the first circulation, and during this period, the embryo is highly sensitive to external influences. The second part, known as the embryonic stage, is characterized by further development of organs and tissues. The embryo becomes most sensitive to teratogenic effects, which can result in structural defects or an increased risk of miscarriage. The third part is characterized by intense growth and development of the fetus, with frequent physiological changes such as uterine contractions, weight gain, and other symptoms preparing the body for childbirth. Childbirth is the process of delivering the baby from the mother's womb, representing a critical moment in the child's development, as events and potential complications during birth can significantly impact their future physical and psychological health. Early childhood encompasses the period from the first to the second year of a child's life. During this time, rapid development of motor, language, and social skills continues. Children become increasingly independent in movement, play, and interaction with their environment. Language skills develop, with an expanding vocabulary and the ability to form simple sentences.
