Kids get upset really quickly, no matter how many of their wishes are fulfilled. They'll always whine and get upset on the one thing a parent refuses to do. Wanting everything their way, is a kid's way of saying "Hey, I'm the boss and you ought to listen to me."
For example, if a family is returning from an amusement park and the kids start crying over how they badly want to have icecream after seeing an icecream truck pass by. Refusing these demands will get the children upset even though this was the only thing a parent refused to do that day. They hardly ever see that a parent has said "yes" to everything else.
Aha Parenting suggests that almost every parent has experienced a situation like that where their kids are behaving entitled. Behavioral economics is a research field and it explored that there are times when humans make irrational decisions while thinking about the world and no one else.
It is important to make a child feel what others must be going through. For example, when a family is at the restaurant and the kids are complaining about the food taking so long, parents should make them understand that maybe the chef has a lot of customers at the moment. Making a child stand in someone else's shoes is the right way to go.
According to the Washington Post, a child should think about other person's feelings as well. Parents should ask them, "How do you think that person is feeling?" Empathy can make a child feel what others are going through. This makes them easy to understand.
Once your child have started to think about others, he/she will be less entitled and will be capable of being more understanding towards everything. These are some ways how a parent can raise their child in an effective manner so that they feel deserving and not entitled.
