What is the consequence with liquid surrounding the fetus?

Amniotic fluid grows and begins to fill, mainly with water, around two weeks after fertilization, is a plentiful source of non-embryonic stem cells.These cells have demonstrated the ability to differentiate into a number of different cell-types, including brain, liver and bone. Amniotic fluid also protects the developing baby by cushioning against blows to the mother's abdomen, allows for easier fetal movement, promotes muscular/skeletal development, and helps protect the fetus from heat loss.
