When I was young, the strap in school was administered by the principal, no-one wanted to be called to the principals office. Although I'm not catholic my first 5 years I went to school at a catholic convent and was taught by the nuns, each nun had a razor strap attached to their belt and if you didn't toe the mark you ended up with pretty sore hands. The strap was outlawed at least in public schools when our kids were in elementary school. Talking to the principal one day he had been all for it but now thought it was one big mistake.
The only time I was punished in school was in grade 2, I had very long pigtails and the girl behind me continued to pull them, I told sister but she did nothing. The next time she tried it I stood up and slapped her across the face. I didn't get the strap but sister gave me a few swats with a cane. All I can say is that girl didn't try it again and stayed clear of me.
Thinking back, I along with all my friends were spanked when we did something wrong, made us think twice about trying it again or anything else that would warrant a spanking. I can't think of any of the kids I knew back then no matter what their background were, whether they were from a well to do family or not all turned out to be respectful, responsible adults, not like today. We had the meaning of respect along with a few other things instilled in us at an early age and yes most of the time it was by way of the "seat of learning"

.
I can't say for others but when my kids were preschool age it only took one smack on the dairy-aire, usually a well padded one if we were out in public. It let them know bad behavior would not be tolerated, knowing what would follow if they misbehaved pretty much nipped it in the bud from then on. It was a joy and actually fun to take them shopping with me. They all learned at an early age wrong choices only led to consequences.
The teenage years were handled by taking away privileges, sometimes it hurt me more than it hurt them. They were pretty good kids compared to a lot in the 70's, and waiting out the time limit on whatever was taken away from them at times was harder on me than on them. Nobody loved their kids more than I did and still do.
In the toddler stage mine always wore a harness, if I stopped to look at something I'd slip it around my leg, Overprotective maybe but they can disappear in a moment and if you have to go looking for them you usually head off in the wrong direction, better to be safe than sorry.
All three of ours have on many occasions, thanked us for the way they were raised, which make me think I couldn't have been too off base.
