I use a switch. My reasons are actually very similar as those who believe in not using any item. With a switch, I don't have to use any pressure, therefore, no actual pain, just a sting. With a hand on a diapered bottom, you usually feel the need to swat three times or more, with a switch, on the upper thigh right below the diaper, there is just enough sting to gain attention, but not so much as to cause a mark or any lasting pain. I don't buy the whole, "the object takes the anger away from the parent and places it on the object" philosophy, but.... I do believe that my children know when they will get a swat. Momma can't just haul off and whap them, I have to get the switch, they see this happen. They won't flinch if I yawn at the dinner table. They won't fear my BARE hand, because they will know that they are only going to get a swat IF I have the switch in my hand.
