Go to your room??
I don't know about other countries but here in the US sending a child to their room is not punishment. Phones, TVs, radios, Ipods, Nenteno, X box, and all the privacy they need to do what ever they want. I might be wrong but that doesn't exactly sound like punishment to me.
An old saying: an ounce of prevention is worth a pound of cure.
A swat on the back side once in a while when their toddlers and you won't have to be wondering where they are when their teens. Beat a child ??? never!! But placing a hand on their back side is not beating.
