Parents everywhere praise their kids. Jenn Berman, author of The A to Z Guide to Raising Happy and Confident Kids, says, "We've gone to the opposite extreme of a few decades ago when parents tended to be more strict." By giving kids a lot of praise, parents think they're building their children's confidence, when, in fact, it may be just the opposite. Too much praise can backfire and, when given in a way that's insincere, make kids afraid to try new things or take a risk for fear of not being able to stay on top where their parents' praise has put them.
Still, don't go too far in the other direction. Not giving enough praise can be just as damaging as giving too much. Kids will feel like they're not good enough or that you don't care and, as a result, may see no point in trying hard for their accomplishments.
So what is the right amount of praise? Experts say that the quality of praise is more important than the quantity. If praise is sincere and focused on the effort not the outcome, you can give it as often as your child does something that deserves a verbal reward. "We should especially recognize our children's efforts to put themselves and work hard to achieve a goal," says Donahue, author of Parenting Without Fear: Letting Go of Worry and Focusing on What Really Matters. "One thing to remember is that it's the process not the end product that matters."
Your son may not be the best basketball player on his team. But if he's out there every day and playing hard, you should praise his effort regardless of whether his team wins or loses. Praising the effort and not the outcome can also mean recognizing your child when she has worked hard to clean the yard, cook dinner, or finish a book report. But whatever it is, praise should be given on a case-by-case basis and be proportionate（相称的） to the amount of effort your child has put into it.
精炼 = 惊艳
There are two extremes of praising: being too strict with the kids and giving a lot of praise.
The former makes kids feel they are not good enough while insincere praise makes them afraid to try new things or take risks.
The point is not the quantity of praise but the quality. We should praise more on kid’s efforts and process instead of the result.
Quantity or quality?
Talking of praise, most people nowadays pay more attention to the quantity of praise, believing that a lot of praise will build their children's confidence while actually too much insincere praise destroys their confidence and courage.
Experts say the quality of praise lies in the proportionate focus on the children's efforts during the whole process, which should be on a case-by-case basis.
