Babies are teaching us the origins of violence

Now that amniocentesis is common, babies in the womb frequently confront a needle entering their private territory. Studies show they react fearfully, defensively, and sometimes aggressively (Ianniruberto and Tajani, 1981). This was brought to my attention again when an acquaintance told us of her experience during amniocentesis. Her husband, the doctor, and the ultrasound technician all saw little Claire bat the side of the needle! The technician said, "Take it out!" When the doctor reinserted the needle, the fetus again attacked it , forcing the doctor to remove the needle. The husband and doctor were in a nervous sweat. The doctor said he had never before seen a baby bat a needle. The parents had an instant lesson in prenatal psychology: they had no idea that a baby this age could sense the intrusion of a needle (and with eyelids fused), have such strong feelings and take such effective action.
