Children should not feel inferior towards what their parents have accomplished. In the same manner, there shouldn’t be any sibling rivalry.
A family is one. They truly love and care for each other. The success of one is the success of all. The failure of one is the failure of all. If one falls, the others do their best to help pull the other one up. That’s what caring is all about.
They are happy for each other’s accomplishments. There is no competition. There is no small success in a family. Parents will always be proud of their children no matter what.
