How do you discipline children ?

It is so hard to discipline children nowadays. We used many approaches: time-outs, removal of privileges, yelling and spanking. Sometimes they works, many time they don't, and we give up. In a survey of more than 2,000 parents of children between the ages of 2 and 11, researchers have found that more than 38% were using the same discipline methods their own parents used on them as a child. Overall, 45% of the parents using time-outs as a disciplinary action. Almost 42% removed their child's privileges, followed by 13% who resorted to yelling and 9% who opted to spank their children. Here is the bummer though- almost 31% of participants reported they believed their methods were not effective !
