Infant Pain

 Taddio (a pain specialist) concluded that a single painful event could produce effects lasting for months, and perhaps much longer. "When we do something to a baby that is not an expected part of its normal development, especially at a very early stage, we may actually change the way the nervous system is wired," she says. Early encounters with pain may alter the threshold at which pain is felt later on, making a child hypersensitive to pain--or alternatively, dangerously indifferent to it.
