How hearing touch and pain smell and taste develop in infancy? According to Piaget’s Cognitive Development Stages: From birth until age two, children are in the sensorimotor period. This is accomplished using all five senses: sight, hearing, touch, taste, and smell. Some senses (such as smell and taste) are at their peak at birth, and hearing matures at one month, while vision develops throughout the first year. According to research, having a newborn’s skin to skin contact after delivery helps the infant recognize the parent’s scent and calms the baby. When a newborn is weeping, it helps them establish a sense of trust and a solid bond to their caregiver. In infants, hearing is less developed, and they require time outside of the mother’s womb to attain their full potential. Simply observe any newborn baby’s reaction to a needle prick during a medical examination to show if they can feel pain. From the moment they are born, newborns are sensitive to changes in temperature, touch, and bodily movements. Over the next several days, these sensitivity levels will rise.
