Importance of mother's milk

During the last 3 months of pregnancy, antibodies from mothers are passed to their unborn babies through the placenta.

This type of immunity is called passive immunity because the baby has been given antibodies rather than making them itself.

Antibodies are special proteins the immune system produces to help protect the body against bacteria and viruses.

Immunity in newborn babies is only temporary and starts to decrease after the first few weeks or months.
