      All parents have skyhigh hopes for their children.We want them to be confident and content.What can parents do to help their kids grow up to lead happy lives? Experts advise:

      1Helping them find their talents.In order to succeed,children need to feel they’re good at

something.So expose your children to as many interests as possible,then let them choose those they like best.

      2Applauding their achievements. A study found  that students whose parents paid attention to

their abilities were far more likely to do well in school-and in life-than students whose parents didn’t show such support.So celebrate your kids’achievements,no matter how small they are.

      3Praising their efforts. Kids won’t always come out on top.Still,they deserve kudos (赞誉) for trying their best.Tenyearold April Cutler,for example,has had trouble with math since second grade.

"She usually gets C’s on her report card,but last year she was determined to get A’s and worked hard at it," says her mom.“When the first grading period ended,April was disappointed when she got a B

minus in math," Lueille continues.“But my husband and I told her we were very proud that she’d

improved.That inspired her to try even harder.She got a B plus for the next period !"

      4Letting them make decisions and mistakes.Making his/her own decisions increases a child’s

sense of control and builds his/her selfesteem  (自尊心).And allowing kids to make wrong decisions-so

 long as doing so won’t harm them-helps kids learn from their mistakes.

      5Encouraging  them to  solve  their  own problems.As they grow,children need practice in

communicating,standing up for themselves and compromising.One of the best places to learn these skills

is at home.So the next time your child runs to you complaining that her brother is blaming her,step back

and let them work it out.
