“My neighbor’s baby doesn’t get a cold for months, but our baby gets a cold several times a month, what should I do? Should I take some immunity-boosting medicine?” Immunity is a word that many parents often mention, thinking that babies are sick because of low immunity. So, what exactly is immunity? How can I improve my baby’s immunity? What is “immunity”? The exact term for immunity is immune system function. It is a sophisticated and complex system composed of a series of immune cells (such as lymphocytes), tissues, organs (such as thymus, spleen, etc.) and immune molecules (such as complement, antibodies, etc.). The “members” of this system work together to combat invaders such as pathogenic microorganisms, which is the main job of the immune system. Why do babies often get sick after 6 months of age? Many parents, especially mothers, have the experience that their babies rarely get sick before six months of age, but after six months, they have frequent colds and fevers. This is because the immunoglobulins that babies get from their mothers are gradually disappearing after 6 months of age, and their own immune system is not established, so they are especially vulnerable to pathogens. Is a baby’s immune system low because it has a cold or fever? When babies often get colds and fevers, many parents think that it is due to their babies’ low immunity. So, is this really the case? It is mostly normal for children to encounter conditions such as colds and fevers during their growth process. Parents always hope that their children will never get sick, the mood is understandable, but it may not be a good thing for the growth of children. Generally speaking, children’s immunity will reach adult levels in their teens. Until then, immunity needs a continuous process of improvement. He will be exposed to a variety of pathogens, and his immunity will battle these viruses and bacteria, and in the process, there may be some symptoms of recurrent whistling infections that manifest as colds, fevers, etc. However, if the child is overprotected and not exposed to the outside environment, the child’s immunity is not nurtured, and once he encounters a slightly stronger bacterial virus, his body will often have difficulty with it. How to improve the baby’s immunity? 1, pay attention to diet Many parents worry that their children eat less, will affect his growth and development, will be malnourished, so often take the “duck-filling” feeding method, but in fact, this practice is not desirable. The child’s organs are delicate, digestive function is not yet sound, eat too much, will increase the burden on the gastrointestinal system, easy for the baby to appear abdominal pain, indigestion and other symptoms. 2, don’t give the child wear too much If parents give the child wear too much or cover too thick, it is easy to sweat, go out and be blown by the wind on a cold. So how much to the baby wear is appropriate? In principle, the child’s clothes should be as much as adults, or less than adults, so that the child’s body to adapt to the cold process, and slowly strengthen the resistance. 3, do not give children abuse of antibiotics Many parents always think that fever is inflammation, see children with colds and fevers, it is customary to use antibiotics. I do not know that 80% of colds are caused by viral infections, and antibiotics have no effect on viruses. And once the antibiotics are used, the child will have some resistance to these antibiotics, and the child will be sick again, really need this antibiotic to reduce inflammation, but it does not work, so parents should not just give children with antibiotics. 4, can allow the child moderate “dirty” Here the “dirty” is not to let people not hygienic, but that do not make the child’s living environment into a sterile state. Some parents have high requirements for the baby’s living environment, cleaning numerous times a day, a variety of disinfection, fearing that the baby stick to a little bacteria, this practice may seem to make the child healthier, but in fact, it is a pathology. If the child has been living in a sterile environment, he will not be able to form resistance to external aggression, just like the flowers in the greenhouse, can not withstand the wind and rain. Therefore, do not let the child live in an environment that is too clean, the right amount of germs will instead promote the development of the child’s immune system, helping him to improve immunity. 5, drink more plain water For children, the best drink is plain water. Children regularly drink some plain water, his mouth, intestines have a certain lubricating effect, can help children better stabilize blood pressure and emotions. 6, proper exercise Exercise is very helpful to improve the child’s resistance, parents can choose the right type of exercise for their children according to the age group.
