The nutrition in breast milk will "change". How many characteristics of breast milk do you know under different circumstances?

Breast milk is the most precious gift from mother to baby, and it is also the most natural and ideal food for baby. It provides all the nutrients needed by baby in precise proportions, and can meet the various nutritional needs of baby's growth and development. And the amazing thing is that the nutrition of breast milk changes with the baby's age.

1. The composition of breast milk can change accordingly with the baby's development needs.

The milk secreted within 7 days after delivery is called colostrum. Colostrum contains more antibodies and other anti-infection proteins and white blood cells than mature milk, which helps prevent infection. The growth factors in colostrum help intestinal development and prevent allergies. Colostrum has a slight laxative effect, facilitates the excretion of meconium, and reduces jaundice. The rich vitamin A in colostrum can also reduce serious infections in infants.

30 days after the birth of the child, the mother's breast milk becomes mature milk. At this time, the breast milk is not only rich in nutrients, but also adjusts the content of nutrients according to the changes in the baby's growth process.

This is because as children grow, the protein concentration required per kilogram of body weight decreases to adapt to the development of various organs in the body, especially the kidneys. This reduction in protein concentration is very reasonable.

2. Nutrition changes as the breastfeeding process progresses.

The nutritional content of breast milk is not constant during each breastfeeding. It changes with the time of day and even before and after a breastfeeding. For example, the milk secreted at the beginning often looks thinner. This part of breast milk is called foremilk. Foremilk is secreted more and is used to quench the baby's thirst. Later, as the baby sucks, the milk will become thicker and thicker. This part of breast milk is called hindmilk. Hindmilk is rich in nutrients and calories and is used to quench the baby's hunger.

3. Nutrition changes with the seasons.

Breast milk will even adjust its composition according to seasonal changes. For example, in the summer when the temperature is higher, the baby's growth and development requires more water. At this time, breast milk will become more water-rich, making it easier for the baby to quench his thirst.

Look, aren’t the changes in breast milk magical? So mothers who can breastfeed must insist on breastfeeding!
