5 year olds can be the biggest assholes on the planet. And there is ZERO excuse for it. Get counciling if they need it, but it's NEVER okay to let them take it out on someone else. And it's certainly not okay to judge others on how they discipline their children if it is obviously non-threatening. Soap in the mouth is harmless and extremely effective because they can make the connection rather easily....you have a dirty mouth and we need to wash it out.
That no-handed approach to raising children is exactly the reason for the topic of this thread. I'm sorry, but my parents never had any problems administering the belt when we messed up and I don't need therapy, I wasn't an abused child, and I have a healthy respect for authority figures. All of this PC crap is nothing but bull ...they are turning out nothing but a bunch of spoiled brats. Cussing at your teacher and implimenting rules to perpetuate it? Give me a break.
