Children grow sick is unavoidable, as long as in a controllable range, it is a good thing, not a bad thing: the child from birth 5-6 months until the age of 5-6 years, during this period of time, need to go through a gradual establishment of their own immunity process, infants in the birth of six months or less, from the mother to obtain immunoglobulin and white blood cells, etc., will be gradually depleted, and then began to grow sick, in fact, this is also the baby began to establish In fact, this is also a process for infants to start building up their autoimmunity. It is not until the age of 5-6 years that the establishment of autoimmunity becomes effective. This is only a generalization, not all infants are necessarily so. Individual infants, who do not receive enough immunity from their mothers, may begin to grow sick in less than six months, and similarly, infants who are weaker and whose inflammation is not effectively controlled may continue to be sick beyond the age of 5-6 years. Therefore, inflammation cannot be cured, but it must be controlled and never left unchecked.
