Most pregnant mothers worry about their unborn babies' safety, but a foetus is actually well-protected in the womb. The amniotic fluid, placenta and mucous plug all serve a purpose in protecting the baby from harm.

Amniotic Fluid

The amniotic sac and amniotic fluid are inside your womb and provide a liquid buffer for your baby. The fluid inside the sac absorbs shock, so that light knocks, bumps or pressure on the mother's belly does not harm the baby. It also protects the baby by regulating the temperature in the womb.


The placenta protects a baby from most bacteria to which his mother is exposed. Also, in the last few months of pregnancy, the placenta passes the mother's antibodies on to the baby, protecting him by giving him immunity for his first three months

Mucous Plug

The mucous plug is in the opening of the cervix. It protects a foetus from any outside contaminants or bacteria.
