It helps to cushion hard blows and jolts to your belly to protect the baby and it allows your baby the freedom to move while permitting symmetrical musculoskeletal development. It also maintains an even temperature so that your baby does not get too hot or too cold, even if you are extremely hot or cold.

mniotic fluid also helps your baby develop his lungs. While in the womb your baby practices breathing by breathing in and out the water in the amniotic sac. The baby swallows and inhales the amniotic fluid and replaces the volume in the amniotic sac by urinating and exhaling the liquid.
