My mom used a flyswatter on our ankles. We knew we were in big trouble if she told us to sit down and roll up our pants legs. She was a teacher and knew that the flyswatter would hurt like a son of a gun but not leave any marks. She didn't want the other teachers thinking she was abusing us when we deserved a spanking. I remember only 2 spankings as a kid and I deserved it both times.
I spanked my kids when they were younger if they truly needed it but I used my bare hand on their bottoms. Now that they are older, they get things taken away and that hurts them way more than a spank. I have also been known to make them write a letter of apology to whomever they wronged and do that person's chores as reparation. They also hate that more than spanking.
