Prenatal Development
Prenatal Development refers to the development of a baby in the womb, a process that takes about 38 weeks. A baby first starts as a single fertilized cell, which grows into an embryo. After 8 weeks of development, an embryo is referred to as a fetus. The prenatal period is a crucial time for physical development, in which the mother should be careful to avoid illnesses, nutritional deficiencies, and toxic substances that can harm the baby.
