The fetus floats safely in amniotic fluid (mostly water, with some salts & proteins). It doesn't "drown" or breathe air—oxygen & nutrients flow directly from mom's blood via the placenta and umbilical cord. Lungs stay fluid-filled until birth; the baby even swallows & "breathes" the fluid to practice. The fluid cushions, warms, and lets it move freely. Nature's perfect setup!
