This happens when the pain nerves are stimulated by some harmful event, such as a finger prick or cut. The emotional experience. This is what the sensory event seems or feels like to the individual person. Many things affect this. They include what we remember from past experiences and have learned from our family and friends, how well we are feeling otherwise at the time, and whether it is a brief, one-time event or will last for an unknown amount of time.
Babies do feel pain.
The emotional experience is not well understood. There are questions about what the sensory event means to the newborn, whether the baby remembers it, and whether it has any effect on the baby after the pain has gone. If there is some obvious painful event, and the baby responds with a change in either behavioral or physiological signs, it seems fairly safe to assume the baby is in pain. However, if there is no obvious event, it is not always easy to tell if a baby is experiencing pain. Babies may show these same behaviors when they are upset or agitated but there is no reason to suspect pain, such as when they are being diapered or are having trouble breathing.
