When children turn three, their self-control increases. They want to please and are highly susceptible to praise. Their increased motor activities enable them to handle larger objects, and block play usually increases their carrying and lifting capacity and contributes to their building skills. Fine motor development of three-year olds progresses further and enables them to pick up small objects easily and adult grasp is stimulated by using crayons to write and color. Play is still an important part of their development, and unlike two-year old children who are involved in parallel play, the three-year old begins to play cooperatively especially when play is structured by their own imaginations.
