Very little is know about an infant's sense of taste but he will definitely react to strong odors by turning away from the odor. As he grows he will notice movement, patterns and also brightness. He will be able to respond very early to movement. It will fully depend on the individual infant as some infants will be more active than others. Newborns also differ in their irritability as some are very peaceful and content and others seem to cry a lot.
Some babies like to be cuddled and others seem to dislike handling and cuddling.
Even at the point of infancy a child's personality for his later years in life will be developing. As he grows you will notice a difference in his physical growth and also his motor development. A baby will learn to control the movements of his shoulders before he can direct his fingers or his arms. He will also gain control over his upper leg before he can manage to control his lower leg of his left foot. The movement and motor ability of a baby will slowly become more controlled and complex in progression from head to toe.
