Hot Wheels race track. (Once, and that's all it took.)
Once! Me and brothers were beat regularly with the race track. :-) Thanks MOM!
Hey, I used to grab one of those when my four boys got out of hand. It was a good tool, and it stung just enough to make them stop what they were doing. And I wasn't a mean mother either, I just needed to let them know who was in charge. Otherwise they would've run all over me.
I remember I had to use it a couple of times on each pre school kid when he disobeyed me and ran across the street. I told him that if he got hit by a car, it was going to hurt a lot more than a couple of swats across the rear end. I did this to get my sons' attention. and it worked. Each one began to understand the consequences of his actions. I'm glad I'm not raising kids in this day and age. I guess I'm lucky, my kids are in their 40's and 50's now.
My dad used to use his razor strap if he felt we got out of hand. That worked good too. After a couple of licks of that we were better behaved. Funny thing in all this, I never once felt I was abused.
