@bold- I was immediately reminded of the end of this scene in A Christmas Story:You can whip them and also explain. When my kids were little if they did something like run into the street, I would do a smack, and then I would tell them I did not want them to run into the street because a car might hit them and then they would be road kill and I would cry and cry.
I only spanked for intentionally hurting someone (the irony), putting themselves or someone else in danger, or direct defiance. And not always then. But I always, always, always explained even when I was pretty sure they were too little to understand. But until (and sometimes after) they get to a certain age you can talk or yell until your jaw falls off and they don't care. What means something to them is consequences and you can't let them face the natural consequences of running into the street or climbing out of their car seats.
But I never did hot sauce. That's weird to me, but maybe that's because I wasn't raised that way. I did a little rub of soap on the tongue, but I made sure it wasn't toxic and tasted it myself first. I usually tested punishments on myself before I did them to the kids. I've known of parents that squirted dish soap into their kids' mouths or spanked bare butts (that weren't already bare). Those aren't things I could be comfortable with, either. And I don't think if I was doing things again now I'd soap their tongues. There are better ways to do things.
