Aches & PainsWho is affected?Children of all ages can experience pain. For a long time, scientists believed that infants and young children didn't feel pain, or didn't remember painful experiences. We now know this is untrue. In fact, studies have shown that by 29 weeks of gestation, pain pathways and the parts of the brain that perceive pain are well developed. Research also indicates that there might be some sex differences in pain response. Girls seem to feel greater discomfort during painful medical procedures than boys. |  |
