Often, kids multitask, or use more than one device at a time. " If you’ve got a chance to do something on your computer and take a phone call and have the TV on in the background, why not?" media expert Cheryl Olson says.

　　Most experts agree technology has much to offer kids. But some worry the kids could be missing out on other activities like playing outside or hanging out with friends. " It' s a matter of balance," says Olson." You’ve got to work on it. "

　　Multitasking while doing homework is another concern. Some kids listen to music, watch TV or use the phone while doing their homework. "It' s important to make sure that you can stop and concentrate on one thing deeply, " says Rideout.

　　With new and exciting devices hitting stores every year, keeping technology use in check is more important than ever. " Kids should try," adds Rideout. " But parents might have to step in sometimes. "
