👉 Baby fluid, also known as amniotic fluid, is a clear, colorless liquid that fills the amniotic cavity surrounding a developing fetus in the womb. This fluid plays a crucial role in fetal development by providing a protective environment, allowing the baby to move freely and reducing the risk of injury. It also helps regulate the temperature around the fetus, facilitates the maturation of the lungs by allowing them to practice breathing movements, and serves as a medium for nutrient exchange between the mother and the baby. The volume of amniotic fluid typically increases as the pregnancy progresses, peaking in the second trimester and gradually decreasing after birth as the baby begins to breathe on its own.
