Children, as any parent knows, are not small adults. Their brains are growing and being acutely shaped by their environment and experiences. Social skills and values are learnt from those around them, with teamwork, risk-management, personal boundaries, and tolerance being learned through play with other children. Their immune system is imprinting environmental contact into a set of responses that will shape health in later life. Their bodies grow physically and become adept at physical skills. They learn both trust and mistrust through interaction with adults.
