“How can I strengthen my baby’s immune system so that he gets less or no illness?” This question is often asked, and there are few parents who think this way. It is completely understandable that parents feel worse than their children when their children are sick. Since this is the focus of parents’ attention, here is the answer to all mothers on the issue of immunity. After a baby is born, the immune system is slowly maturing. A baby’s immune system consists of two major components: innate immunity and acquired immunity. 1. Innate immunity Innate immunity is the natural immunity that everyone has at birth, and it has a comprehensive protective effect. Before the transmission of antibodies from the mother via the placenta and breastfeeding after birth. 2.Acquired immunity Acquired immunity is gradually acquired as the baby grows, and is developed gradually through the stimulation of infectious germs, vaccination and the soundness of the intestinal flora status. When invaded by pathogenic microorganisms or after receiving immunization, the body will produce special antibodies against such pathogenic microorganisms, and later, when invaded again by such pathogenic microorganisms, the antibodies can combine with other immune cells and so on to kill the pathogenic microorganisms. 1, baby often fever, is not the immune system is low? Fever is a symptom, not a cause. When a child has a fever, you should look for the cause. Do not assume that a child with frequent fever must be immunocompromised. The most taboo approach is to choose antibiotics + antiviral drugs + immune boosters once the child has a respiratory infection, which is very detrimental to the maturation of the immune system, but will bring damage. 2, baby allergic to milk, is not the immune function is not good? Allergy itself is a manifestation of abnormally enhanced immune function, not low immune function. Children with milk allergy should avoid milk and its products, and use deeply hydrolyzed or amino acid formula to ensure the source of nutrition. When you start adding complementary foods, you can add them gradually according to the child’s acceptance in order to find a recipe that the child can accept. 3. My child has had pneumonia several times, is there something wrong with the immune system? In addition to respiratory symptoms, a diagnosis of pneumonia should include chest x-ray results and then pathogenic test results. Do not easily diagnose pneumonia with fever + cough + sputum. And even if it is pneumonia, it does not have to be a bacterial infection. As long as the child does not have recurrent bacterial infectious pneumonia, it does not mean that there is a problem with immune function. 4.Do I need to give my child some immune boosting medicine if he has asthma? The common cause of asthma is allergy, and allergy is a manifestation of immune enhancement. If we then improve the resistance, the allergy will be more serious. To treat asthma, the first thing you should do is to find the cause of the allergy, and removing the allergen is the main way to cure it. Antibiotics should not be chosen for asthma attacks, unless they are combined with bacterial or mycoplasma infections, and broncholytic drugs and corticosteroids should be used. 5.Does my child need immune boosting treatment if he/she is frequently sick? A child who does not have recurrent bacterial infections is not immunocompromised. Do not assume that if your child has had an infection, he or she is immunocompromised. The immune system includes both innate and acquired immunity. Acquired immunity is what occurs after constant stimulation after birth, so parents do not have to take any kind of treatment to improve immune function in normal children. 6.I heard that antibiotics can destroy the immune system, why? If a child develops a cold, it is important to determine if it is a bacterial infection. Repeated, aggressive use of antibiotics, instead of boosting your child’s immune function, can destroy it. Therefore, the more aggressively a child is treated with antibiotics, the more likely the child will get sick, because sickness itself stimulates the maturation of the acquired immune system, and antibiotics will weaken it. 7. Is breastfeeding a way to improve the baby’s immunity? Before the birth of a fetus, the mother transmits her own immunoglobulin IgG to the fetus through the placenta, and these IgG can stay in the baby’s body for about 6 months. After the baby is born, the mother feeds her baby a continuous supply of IgA antibodies produced in the intestinal and respiratory tracts through breastfeeding. Moreover, there are many nutrients in breast milk that are biologically active, which can promote the maturation of the baby’s immune system as soon as possible. 8.How to protect the baby’s immunity? Protecting your child’s skin will ensure that the first defense barrier of the immune system is built, so it is not necessary to clean your child’s skin too carefully every day. It is recommended to bathe your child every day, but it is not recommended to use body wash every day and use moisturizer after bathing. Only for children with dry skin can you choose a moisturizer of plant origin. 9.Why can taking probiotics improve immunity? The role of probiotics is to improve the intestinal flora. The intestinal flora is improved, not only for digestion and absorption, but also to improve the immune function of the intestine. The enhancement of intestinal immune function will in turn stimulate the enhancement of systemic immune function. Therefore, the first item of the indications for a real probiotic preparation should be to improve the immune function. In order to regulate immunity by probiotics, it should be taken for at least 3 months. Breastfeeding is bacterial feeding, inhaling bacteria around the nipple and in the milk ducts, which not only facilitates the establishment of the child’s intestinal flora, but also promotes the maturation of the systemic immune system by stimulating intestinal immunity. Formula feeding will lack the bacterial process of breastfeeding, so formula-fed babies should have active probiotics added appropriately, which is the reason why some infant formula has probiotics added within it. 10.What vaccinations should be given to babies to improve immunity? Vaccination is a very good way to stimulate acquired immunity. Vaccines are fragments of bacteria and viruses or important fragments of them that prevent really serious infectious diseases by stimulating the immune system in the child to produce the appropriate antibodies. Therefore, there should be no talk about which vaccines should be given and which ones should not be given. Planned vaccines are free of charge and unplanned vaccines need to be given at one’s own expense, independent of the importance of the vaccine. 11.Can I give my baby immune-boosting drugs? Immune boosters should never be given to children casually, unless the child has been identified as immunocompromised. Never assume that a child who has frequent colds or has had several bouts of pneumonia is immunocompromised; there are objective indicators of immunocompromise. If a child has mild allergies and then uses an immune booster, it can amplify to severe allergies.
