During this time of their lives, children are constantly experiencing new things and embarking on new adventures. New surroundings, new friends, new experiences - every day, children see and learn something new. As they make their way through school, their bodies are continuously confronted with new microbes.

Children's immune system often put to test when they start or change day care or school. The number of infections often increases during this tie, because sick children often do not stay at home and can infect other children. Children are in close contact with others, especially in kindergarten and the early years of school, making them more susceptible to adverse conditions. Parents can help by encouraging regular hand-washing, teaching children to keep toys out of their mouths, keeping children at home when sick to protect others, and supporting the child’s immune systemin autumn and winter seasons.
