I know I've stated this before when we've talked about it, but, yes, I am beating that behind!
We started early as far as disciplining our children. You have to get a hold of them early. When they were very young, I was one of those "beating in public" (more of a pop, "whoopings" occured in the bathroom) moms that some of you dread. It let my children know, if you show off in public, I'm getting you in public. I remember once, my son had the audacity to show off in front of a policeman. Hmmmmmm. He got "popped" right in front of him, no questions asked.

I see alot of manipuative children that
know bad behavior embarrasses the parent show off in public
on purpose.

They worry about sufferring the concequences later. Now that my children are older, all I have to do is look at them and that ends the madness in public before it begins.
