In their more benevolent living form the spurs are intended by mother nature merely to allow the offspring to hitch a ride. After death when their dried up husks fall to the ground the spurs are especially worrisome since they may become contaminated with animal feces and e-coli that can be introduced beneath the skin and into the blood stream. Serious and unwanted infection can result in addition to the pain.
Best to vent your anger at the sand spur plant and its offspring for your child being stabbed rather than at your child or another human being. This is best accomplished by dealing with the spurs while they are alive and still attached to the plant.
