Newborns can get antibodies from their mothers.

Newborns can get antibodies from their mothers, and the antibodies obtained from breast milk are IgA antibodies. Newborns have a high demand for nutrition, but their digestive and metabolic functions are limited. Proper mastery of reasonable nutrition has the most decisive influence on enhancing physical fitness and resistance. The following is about how newborns get antibodies from their mothers.

Antibody 1, which can be obtained by newborns from their mothers, refers to globulin that can specifically bind to antigens and can neutralize toxins, sterilize and dissolve bacteria. If the newborn wants to absorb it, it can promote the body to produce antibodies through maternal transmission of antibodies and breast milk absorption antibodies.

1, mother-to-child transmission antibody: antibodies existing in newborns, that is, immunoglobulins, such as IgG, IgA and IgM. Among them, IgG can be directly transmitted from the mother to the fetus through the placenta, so a large number of immunoglobulin IgG has been obtained from the placenta at birth, and this part of immunoglobulin can generally reach a certain balance in the body and can be maintained in the newborn for 6 months.

When the newborn is 6 months old, this part of immunoglobulin is gradually consumed, and it is necessary to rely on the immunoglobulin produced by the newborn itself to gradually maintain the immune function of the body;

2. Absorb antibodies in breast milk: Newborns can obtain part of immunoglobulin IgA through breast milk, and the antibodies contained in breast milk mainly include secretory immunoglobulin IgA. Immunoglobulin IgA is mainly located on the surface of respiratory mucosa. After the newborn gets immunoglobulin IgA from breast milk, it will improve the immune function of respiratory tract, thus reducing the chance of respiratory tract infection.

Generally speaking, milk contains more immunoglobulin IgA within 1 week of delivery. Therefore, it is necessary to breastfeed as soon as possible after birth 1 week to obtain a higher content of immunoglobulin IgA in breast milk;

3. Other routes of absorption: For immunoglobulin IgM, due to its large molecular weight, it cannot be transmitted through placenta or breast milk. Newborns can gradually produce antibodies by vaccination to ensure balanced nutrition and sleep.

When did the antibodies that newborns got from their mothers begin to disappear?

During pregnancy, the placenta transports immunoglobulin and other substances to the fetus, which constitutes the first defense system for newborns to resist infection. After the newborn is born, antiviral immunoglobulin can be obtained from breast milk. In addition, newborns are usually well protected and have less exposure to pathogens, so babies are less sick within 6 months.

However, with the passage of time, the antibody substance obtained from the mother is gradually consumed after 6 months, and the immunoglobulin concentration in the baby drops to the lowest point. At this time, although the baby's own antibody level is slowly improving, it is not enough to make up for the consumption.

At the same time, the baby's immune organ development is not perfect, the immune system can't provide enough immunoglobulin, the function of phagocytosis is not perfect, and the composition of "complement" in serum is also very low, so it can't cooperate with antibodies to prevent the invasion of pathogens.

Therefore, the resistance is extremely poor, and it is easy to get sick, and it has entered the so-called "physiological immune deficiency period" in medicine. At this time, the baby is prone to diarrhea, colds, pneumonia and other symptoms, and it is more difficult to avoid being attacked in the season of high incidence of epidemic diseases.

In addition, it is also closely related to the development and maturity of the immune system. Generally speaking, from 6 months to 1.5 years old, the baby's ability to produce antibodies has been initially formed, but it is far from reaching the adult level, and the number of infected diseases increases at this stage;

1.5 ~3 years old, the antibody level in the baby has reached about 70% of that in adults, and the white blood cells are gradually maturing, but because of the expansion of contact with the outside world, the chance of infection with pathogens increases; 6 months to 3 years old is also the stage when children love to get sick; By the age of 4~6, immune cells and molecules such as T lymphocytes, macrophages and neutrophils in the body, such as complement and lactoferrin, also mature with immunoglobulin, and the frequency of many babies who are often sick gradually decreases; After the age of 8, the resistance of the whole immune system has been equivalent to that of adults, and the frequency of illness has dropped significantly.

Newborns can get antibody 2 from their mothers. Breast milk is the most suitable natural food for babies, which has many benefits for babies. First of all, it can protect babies from diseases. The more breast-fed, the more protection they provide. Breast milk is rich in antibodies, which can promote the development of baby's immune system. Breast milk can also kill cancer cells and other germs, making babies show high IQ from birth to early adulthood.

In the process of breastfeeding, the use of milk powder and related AIDS is reduced, so breastfeeding can reduce the economic pressure and enhance the feelings of mother and baby in the process of breastfeeding, which is very beneficial to the whole family and society. Because the use of milk powder and auxiliary products is reduced, it also has a very good effect on environmental protection.

"Give the baby enough nutrition and antibodies to keep the mother in good shape. Breast milk is the only natural, safest and most complete natural food during the baby's growth. It contains all the nutrients and antibodies that babies need for growth. In particular, breast milk contains 50% fat, which not only supplies the baby with body heat, but also meets the fat needed for the baby's brain development (60% of the brain structure comes from fat). Rich in calcium and phosphorus can make the baby grow tall and strong;

Immunoglobulin can effectively prevent and protect infants from infection and chronic diseases; Bifidobacterium and oligosaccharide can inhibit the reproduction of intestinal bacteria and help digestion. In addition, the intimate contact and parent-child relationship of breastfeeding can stimulate the baby's brain and intellectual development, and breastfeeding can promote the contraction of the mother's uterus and maintain a good figure, so breastfeeding is of great benefit to both the baby and the mother. "

Breast milk is good for both children and mothers.

First, breastfeeding can provide enough nutrition for babies, and breast milk is easy to digest and absorb, which can promote children's growth and development.

Second, breastfeeding can enhance children's immunity and reduce neonatal infectious diseases, especially respiratory and intestinal diseases.

Third, breast-feeding can also promote uterine contraction, reduce postpartum hemorrhage, help mothers regain their body shape, help women consume fat stored during pregnancy and help women lose weight.

Fourthly, breastfeeding can also reduce the incidence of breast cancer and ovarian cancer.

Fifth, breastfeeding can enhance the relationship between mother and child.
