The easy way to "lead" a child is by saying DO and DO NOT. I tell you in that case you will get in stress and your child do either. Remember, a child has a passion to know what’s new. Whatever! If that so the rule, why don’t we realize that fact?
We can not do teaching any kind of moral to a child efectively as they are a small adult people.
They are Children, with their way of thinking in growing. Teach them by doing like children. If you do like this you will find something different in teaching children.
Try not use Do and Do not. If you have to use such words, explain it Why and Why.
Be a teacher by a leader.
