As I said, I don't dole out any kind of punishment when angry. I made that the rule when I realized I was saying things like "you are grounded until your forty" or some such. Its too easy to give a punishment without thinking it through and giving something that just is not going to work, is too much or is unreasonable for the actual crime. I see spanking as no different than any other punishment and as such, it fell under my rule of no punishments when angry.
As has been said over and over,
I was not hitting my kids, slapping my kids or beating my kids. They got 3 or 4 swats on the butt. They knew ahead of time it was coming and they knew why. And they know they are loved above all.
And as other have said, probably were
well prepared for it with all the layers of underwear.
ETA: I used this same rule as a preschool teacher/child caregiver. We didn't spank but used time out, rewards, and other discipline techniques. BUT, if a child did something that made their teacher/caregiver angry either the child or the teacher was removed from the classroom/area until the teacher/caregiver was no longer angry; then she could talk to the child and use whatever techniques was appropriate--usually only took, at the most, 2 minutes but helped a lot.
