The eye level talk

This method has been working well so far.
Instead of yelling, shouting to your kid, kneel down until you are at the same height as him, having eye to eye talk.To get his attention, squeeze his arm but don't hurt him, just enough to get him sees your eyes and then say what's your point, e.g. "you cannot draw on the chair, ok?" and teach him to reply "ok" to you. He will listen to you because he feels respected.

I told my hubby to try this technique. I told him that it works for me. So he tried.
and it worked. :)
