When I take my three-year-old son to the park, I watch some mothers obsessed with their son not staining clothes, not getting wet, not running away, not running ... So many NO that the child has almost no chance to play.
A child who returns home from the park is a child who has enjoyed, has discovered his environment and therefore is stimulating his physical, cognitive development, and his immune system.
The infant by nature is a "little scientist"; One of the characteristics of childhood is curiosity, exploring and discovering the world; qualities also present in adult researchers and therefore our children to be able to investigate must be in contact with the object of their interest: water, sand, insects, etc. In addition to developing intelligence, being in contact with nature makes them stronger against microbes. The latest research shows that being in contact with some microbes allows the immune system to learn to recognize them without developing hypersensitivity.
The immune system is like a policeman: it attacks those viruses and bacteria that can harm the body. But since an individual is subjected to an extremely sterile environment, the immune system will not be able to differentiate the "good" from the "bad" bacteria and will respond equally to all creating health problems.
