Many parents are victims to the problem of stubborn kids. No matter what you do they refuse to listen to you They lie down on the floor of the supermarket, start crying and shouting. To sum it in simple world they refuse to listen. What I would suggest is if your in such a situation is not to scould or beat the kid. The best way to tackle the problem is to sit and discuss it with the child. Make the child feel like a grown up and make him or her learn to compromise. If the kid still does not listen then ignore his or her tantrums. The kid will do anything to demand your attention, just look at him or her. In the end the kid will give up for sure.
This is something which has been seen done by a family member and it actually works..
