Tough Love vs. Smacking
Most people think it improper to smack children, so I have tried other methods to control my children when they have one of 'those moments.'
One that I found effective is for me to just take the child for a car ride and talk.
Some say it's the vibration from the car, others say it's the time away from any distractions such as TV, Video Games, Computer, IPod, etc.
Either way, my children usually calm down and stop misbehaving after our car ride together. Eye to eye contact helps a lot too..
I've included a photo below of one of my sessions with my son, in case you would like to use the technique.
This works with grandchildren, nieces, and nephews as well.
