What are antibodies, and how do they help my baby’s immune system?
Antibodies are present in the blood and help to fight infections. Babies are born without resistance to infection and take some time to build up their own immunity. Mature breast milk contains high levels of antibodies, giving your baby protection, particularly in the first few weeks when he is most vulnerable to infections. As your baby spends more time in the outside world, his immunity will grow both from the antibodies received from your breast milk, as well as the ones formed on his own.
