Child development is a process every child goes through. This process involves learning and mastering skills like sitting, walking, talking, skipping, and tying shoes. Children learn these skills, called developmental milestones, during predictable time periods. Children develop skills in five main areas of development: 1  Cognitive Development. This is the child's ability to learn and solve problems. 2  Social and Emotional Development. This is the child's ability to interact with others, including helping themselves and self-control. 3  Speech and Language Development.
Physical development refers to physical changes in the body and involves changes in bone thickness, size, weight, gross motor, fine motor, vision, hearing, and perceptual development. Growth is rapid during the first two years of life. The child's size, shape, senses, and organs undergo change. As each physical change occurs, the child gains new abilities. During the first year, physical development mainly involves the infant coordinating motor skills. The infant repeats motor actions which serve to build physical strength and motor coordination.
