Children are close to our hearts. They are vulnerable and must be protected but should also be exposed to new experiences and surroundings so that they can learn and develop into well-adjusted and balanced adolescents and, finally, mature adults. Parents provide a loving environment, nourishment, and shelter to the child. But supplying food, furniture, strollers, car seats, toys, and clothes for babies, kids, and teenagers is big business as well. Anthropometric, biomechanical, physiological, and psychological information is available to design environments properly so that they are safe and suitable for the body and mind of a child.
