Just to add more to the article.

Placing a child in timeout isn't enough. Children can do no wrong, what trouble they get into is a learning experience and is to be treated as such. The little child looks up to you with those big round eyeballs like windows waiting for you to fill them with something. Spanking and unnecessary timeouts with out a discussion closes those windows.

Spanking or timeouts, chose one or the other as your method and be consistent about it. If you start with timeouts then one day choose to spank that child will perceive it as you just hitting them. I choose not to spank because it sets a double standard for you trying to teach your child not to hit other kids. That double standard hurts your credibility with your child.

After a child is finished with their timeout, it is up to you as the parent to talk to them for a bit after the timeout. If you chose spanking as your method, you have to explain to them why they were spanked. Children are more receptive to those who have not cause them harm and spanking is harming. Keep that in mind.

Ask them if they understood why they were put timeout. Let them explain and respect their explanation and follow up with adding just a little more to their explanation.

If you spank or put a child timeout for misbehaving then release them from timeout with out the discussion then nothing is taught. You not only wasted the child's time but you also wasted and opportunity to teach.
