Every kid is different, and parents should know this better than anybody. That’s why it gets tricky when praising one child for something you wouldn’t praise the other for. If one kid is a diligent, high-achieving student, you wouldn’t praise them for getting a C in Biology. But if your kid struggled immensely with passing even one biology test, you will hang that C on the refrigerator for all to see. 

It’s easy to see the lack of justice in expecting an A from one kid and praising a C from another. Still, the lines can get blurrier when praising kids for accomplishments in their extracurricular activities. If a parent is constantly going out of their way to cheer at one kid’s soccer games but can’t bother to show up and clap during their other kid’s band concert, it will breed resentment in the family at all levels.
