The living environment of 1 should not be too clean, and a small amount of bacteria can promote the normal immunity of the body. In fact, if the baby is exposed to a "dirty" environment, the baby will be stronger.
After birth, only when people are exposed to bacteria can the immune system regulate immunity and resist infection, and the human body itself has a system to regulate allergic reactions. If people are in a clean environment all the time, they can't produce anti-infection function, and their immune system can't play its role, so they are more vulnerable to germs. Human growth is accompanied by pathogens such as germs and viruses, which will make people sick and contribute to the healthy development of human natural defense system.
Mom and dad should take the baby outdoors, get in touch with the sun, get close to nature, and let the baby get in touch with the soil, grass and sunshine. This is actually very meaningful to enhance the baby's resistance. Being exposed to nature outdoors will make the baby feel very happy and helpful to the baby's body and mind.
