Breastfeeding is an important strategy to ensure a healthy balance of good bacteria in an infant’s gut.
Babies have legions of microbes that set up shop in their guts, skin, and more right from birth. These microbes are vital. They help the growing human to digest its food, and to keep harmful microbes away. They are so important that newborns temporarily suppress their own immune system to give their microbial partners a chance to establish themselves.
