It is the main way newborn babies get their food. This milk is full of many important things like fats, proteins, and carbohydrates. It also has many vitamins and minerals that help a baby grow. Beyond just being food, it helps protect babies from getting sick. It contains tiny things like bacteria and immunoglobulin A to help the body fight germs.

The way milk is made is a very interesting process. After a baby is born, hormones called prolactin and oxytocin tell the body to make milk.

At first, the body makes a thin, yellowish fluid called colostrum. This first milk is very high in protein and antibodies. These antibodies help coat the baby's insides to protect them from infection. As a few days pass, the milk changes into mature milk. It becomes thicker, creamier, and has more fat as the baby drinks.

People have studied how to feed babies for a long time. In the 1950s, some countries thought using formula was better than breastfeeding.

However, we now know that no formula can replace breast milk perfectly. Organizations like the World Health Organization and UNICEF give important advice today. They say babies should have only breast milk for the first six months. After that, babies can start eating solid foods while still drinking milk. This can continue until a child is two years old.

There are many specific facts about what is inside the milk. Breast milk is made of 0.8% to 0.9% protein and 4.5% fat. It also contains 7.1% carbohydrates, which are mostly a sugar called lactose.

Some proteins, like alpha-lactalbumin, can even help protect babies from cancer. Scientists also found that milk has special sugars called human milk oligosaccharides. These help the baby's gut microbiome, which is the community of tiny living things in the tummy.

Feeding a baby can happen in many different ways. Most babies can latch onto the breast within one hour of being born.

If a mother cannot nurse directly, she can use a breast pump. The milk can then be put into a bottle, a cup, or even a spoon.

Using a cup can sometimes help a baby continue breastfeeding for a longer time. This is very helpful for preterm babies who might find it hard to suck at first. All these methods help make sure the baby gets the nutrition they need.
