Whenever we go to market, our son always have some demand. This time, he has a demanded a football field set that costs Rs 17000. How do we make him understand that he cannot get whatever he wants? Should we make him understand the concept of 'expensive things'?

I hope this will work on your family too. Instead of buying stuff, make them to work and earn toys. If they helps with house chores, they will get points. Then if the points reached, they can ask for something. That method works well on me and my sister. Wish you all the best
