A few days ago some friends came over with their children, our 6 year old and theirs were making the most of it and I decided to dish out some discipline.
I heard somewhere that when a child misbehaves you use the time-out method for their age in minutes (2 minutes for a two year old etc.), however they were just fooling around and I felt 6 minutes was a bit extreme, so I sent him to our room for 2 minutes. When he came out I told him that each time he misbehaves he’ll have to stay in our room for double the time he spent last time.
The advantage of this method is that, if you stick to it, by the time your child misbehaves for the 23rd time he’s no longer legally your responsibility.
