Does anxone still use spanking?

Find constructive solutions. If you spank the children you will learn to regret it. Encourage their good acts and creativity. If they have to be punished don't carry it over beyond the moment. Set a good example by your own actions.

The best way to discipline children is to take away a privilege/treat.

Kis need to be rewarded for good behaviour.

Physical punishment isn’t the way. It shows a lack of creativity. Violence breeds more violence and resentment. It will prove to be a regretful act. Taking privileges away such as removing video game time may be effective.
