Gestation is the carrying of an embryo or fetus inside female viviparous animals. It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time (multiple gestations).
Appropriate for gestational age (AGA) Gestation is the period of time between conception and birth. During this time, the baby grows and develops inside the mother's womb. If the baby's gestational age findings after birth match the calendar age, the baby is said to be appropriate for gestational age (AGA) AGA babies have lower rates of problems and death than babies that are small or large for their gestational age.
