1 . Too much screen time for kids can lead to poor health the American Heart Association (AHA) says. A scientific statement published by the AHA in the medical journal Circulation said screen time from smartphones, tablet computers and other devices can lead kids to a sedentary(惯于久坐不动的) lifestyle ,increasing the possibility that they grow up as overweight or obese(肥胖的).

The AHA is the latest organization urging parents to limit how much time their kids spend in front of screens. It recommends children get one to two hours of screen time each day. Although television viewing among children and teens has dropped, the use of smartphones and tablet computers has surged.

“Although the mechanisms(机制) linking screen time to obesity are not entirely clear, there are real concerns that screens influence eating behaviors, mainly because children don’t notice when they are full when eating in front of a screen,” said Tracie Barnett, a researcher at the INRS-Institut Armand-Frappier Research Centre,in a statement.

Barnett, one of the authors of the statement, also urges parents to keep screens out of kids’bedrooms, raising the fear that too much screen time can affect sleep.

Many studies have warned about the potential (潜在的) negative effects of too much screen time. Last year, a study from researchers at San Diego State University(SDSU) found nearly half of teens who spent five or more hours in front of screens every day experienced long periods of hopelessness or sadness.

Apple, who makes the iOS mobile platform, plans to introduce new tools to devices to help users cut back on screen time. As for iOS 12,iPhones will include a screen time feature where users can control and review how they spend time on their mobile devices. Another company that makes the Android platform will introduce “digital well-being” tools such as screen time limits and a “wind down” option to encourage users to put down their phones before bed.

3 . Two parents in very different circumstances (境况) told me their worries. One was a Google executive in New York City, who said, “I’m worried that my kids are growing up with too much money. How do I keep them from throwing their money around?” The second was a single mom from Los Angeles. She explained that her son was asking her for $150 jeans so that he could fit in with the cool crowd, and she didn’t know what to do.

To both parents I gave the same answer: Start talking about the value of money, the same way you’d teach your kid to tell the truth or be kind to others. Make sure they know what matters most to your family when it comes to money. Yes, we could afford fancy jeans, but they're not a priority for us.

When it comes to day-to-day lessons, the best way to teach your kids the value of a dollar is to give them actual dollars. When my daughter was 13, she wanted to go shopping with friends for back-to-school clothes. The other parents gave their girls a credit card or a debit card (借记卡) with a spending limit. Me? I embarrassed my daughter by handing her $50 … in cash. The reason: I knew that when she got to the checkout line with more than $50 worth of goods, she’d have to make hard choices and put something back.

Additionally, sometimes it’s what you don’t do for your kid that counts. I will never forget the brave audience member at an event who asked me the question: “Should I get my son an Amex Platinum card? All his friends use theirs to get into first-class airport lounges (等候室)when they travel.” “No,” I said. Always remember, you’ re the parent. You set the rules. And the rules will determine how your kid values money in the future.
