Child on truck

All children go through stages of social development. An infant or very young child will play alone happily. If another child wanders onto the scene, he or she may be physically attacked or pushed out of the way. Next, the child is able to play with another child, gradually learning to share and take turns. Eventually the group grows larger, to three or four children. By the time a child enters kindergarten, he or she is usually able to join in and enjoy group experiences
