Breast milk

Moms make milk to feed their babies.

This milk is very good food. It has fats and proteins. It also has vitamins.

The milk helps babies grow. It also helps them stay healthy. It can fight off germs.

At first, the milk is thin and yellow. Later, it becomes thick and creamy. This helps the baby feel full.

It is a special way to help a baby grow strong.

Moms make milk to feed their babies. This milk comes from glands in the breasts.

This milk is a great source of food. It has fats, proteins, and sugars. It also has vitamins and minerals.

At first, the milk is special. It is a thin, yellow fluid called colostrum. This milk has antibodies. Antibodies are parts of the body that fight germs. This helps protect the baby from getting sick.

As time goes on, the milk changes. It becomes thicker and creamier. The fat in the milk also increases. This helps the baby feel full.

Some moms use a pump to take milk out. They can then put the milk in a bottle.

Experts say babies should have only breast milk for six months. After that, they can eat solid foods. They can keep drinking breast milk up to two years of age. This helps them stay healthy and strong.

Breast milk is a special liquid made by the mammary glands in a woman's breasts.

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.

These details show how much work the milk does for the baby.

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.

Breast milk is the primary source of nutrition for newborn infants. It is produced by the mammary glands in the breasts of women. This liquid is much more than just food for a growing baby. It contains a complex mixture of fats, proteins, and carbohydrates. It also includes a varying composition of vitamins and minerals. Beyond nutrition, breast milk provides essential substances to protect infants from infection and inflammation. These include microorganisms, symbiotic bacteria, and immunoglobulin A.

The production of milk is controlled by specific hormones. After childbirth, the hormones prolactin and oxytocin trigger the body to produce milk. The very first milk produced is called colostrum. Colostrum is a thin, yellowish fluid that is rich in protein and antibodies. It provides passive immunity to the newborn while its own immune system is still developing. Colostrum also acts as a mild laxative to help the baby pass meconium. This process helps prevent the buildup of bilirubin, which can cause jaundice.

As time passes, the composition of the milk changes significantly. In the first three to four days, the milk is thin, watery, and tastes sweet. Eventually, it transitions into mature milk, which is thicker and creamier. While some people used to distinguish between "foremilk" and "hindmilk," scientists now know there are not two separate types of milk. Instead, the fat content simply increases gradually as the baby breastfeeds.

This means the milk becomes fattier and fattier over the course of a single feeding.

The chemical makeup of human milk is very precise. It consists of 0.8% to 0.9% protein and 4.5% fat. It also contains 7.1% carbohydrates, which are mostly made of lactose. Other minor components include human milk oligosaccharides, which are special sugars. These sugars help develop the infant's gut microbiome, which is the community of microbes in the digestive tract. The milk also contains 0.2% ash, which represents its mineral content.

Breast milk offers many long-term health benefits for both the mother and the child. For infants, breastfeeding is linked to a 73% decreased risk of sudden infant death syndrome. It can also decrease the likelihood of middle ear infections, asthma, and eczema. Some proteins, such as alpha-lactalbumin, may even help protect against cancer. In the stomach's acidic environment, this protein can form a complex called HAMLET that kills tumor cells. For mothers, breastfeeding helps the uterus return to its pre-pregnancy size. It can also reduce the risk of breast cancer and certain types of diabetes.

Global health organizations provide specific guidance on how much milk an infant needs. The World Health Organization and UNICEF recommend exclusive breastfeeding for the first six months of life. During this time, breast milk is the sole source of nutrition. After six months, safe and nutritious solid foods should be added. This is because an infant's energy requirements begin to exceed what milk alone can provide. Breastfeeding is recommended to continue up to two years of age.

There are several ways to provide breast milk to an infant. Most newborns can latch onto the breast within one hour of birth. However, globally, sixty percent of infants are not breastfed within this first hour. If direct breastfeeding is not possible, milk can be expressed using a breast pump. This expressed milk can be given via a bottle, cup, spoon, or even a tube. Using a cup can actually improve breastfeeding outcomes compared to using a bottle. For mothers who cannot produce enough milk, pasteurized donor milk or commercial formula are options.
