A baby’s immune system is immature when they are born. It develops throughout life as they are exposed to different germs that can cause disease.
What antibodies are passed from mother to baby?
During pregnancy, mothers transfer to the foetus immunoglobulins (Ig) that recognize antigens to which she has been exposed . IgG is the main Ig isotype transferred across the placental barrier [3-5], and its subclasses are ordered according to their relative serum levels: IgG1 > IgG2 > IgG3 > IgG4.
Does freezing breastmilk kill antibodies?
Freezing kills antibodies, so rather than freezing all of your pumped milk, feed as much fresh or refrigerated milk as possible. But even without the antibodies, frozen milk is still a far healthier choice than formula.
