Set expectations too high.
Parents have high expectations for their children's efforts. When their children can't meet these expectations, parents will be disappointed. In fact, children may have done well, but parents' expectations are too high.
Unrealistic expectations
Parents have unrealistic expectations for their children's gratitude. Parents will be disappointed when their children can't meet these expectations. This is actually not the fault of children, but the result of parents' high expectations.
Lack of educational methods
Correct educational methods are the key to cultivating grateful children. Although some parents have paid a lot, due to improper educational methods, children will not be grateful. Therefore, parents need to examine and adjust their own educational methods in order to cultivate truly grateful children.
