This is an often overlooked aspect of abortion. Judging from the unborn child's response to stimuli at this point, abortions have often been quite painful, and they have almost certainly been more so in the past. Years ago the leading method of late abortion involved injecting a caustic salt solution into the amniotic sac. There's little in the way of a dead layer of skin to protect the baby at this point, so it would be like salt in an open wound. It would take more than an hour to kill the baby this way, during which time nothing is being given for the pain, and there have even been instances where the baby has survived long enough to be born alive. This procedure has largely been abandoned because of the risk to the mother's health, but there are still occasional instances of its use.
