Just as adults have a hard time putting down their iPhones, so the device is now the toy of choice for
many 1- 3 years old children. It's a phenomenon that is attracting the attention of some childhood
development specialists.
     Natasha Sykes, a mother of two in Atlanta, remembers the first time her daughter, Kelsey, then
barely 2 years old, held her husband's iPhone. "She pressed the button and it lit up. I just remember her
eyes. It was like 'Whoa!' "The parents were charmed by their daughter's fascination. But then, said Ms.
Sykes, "She got serious about the phone."Kelsey would ask for it. Then she'd cry for it. "It was like she'd
always want the phone," Ms. Sykes said.
     Apple, the iPhone's designer and manufacturer, has built its success on machines so simple and
intuitive(直观的) that even technologically confused adults can figure out how to work them, so it makes
sense that expert children would follow. Tap a picture on the screen and something happens. What could
be more fun?
     Many iPhone on the market are aimed directly at preschoolers, many of them labeled "educational,"
such as Toddler Teasers: Shapes, which asks the child to tap a circle or square or triangle; and Pocket
Zoo, which broadcasts live video of animals at zoos around the world.
     There are "flash cards" aimed at teaching children to read and spell, and a "Wheels on the Bus"
program that sings the popular song in multiple languages. Then there's the new iGo Potty program, with
automated phone calls reminding toddlers that it's time to "go ".
     Along with fears about dropping and damage, however, many parents sharing iPhones with their
young ones feel guilty. They wonder whether it is indeed an educational tool, or a passive amusement like
television. The American Academy of Pediatrics has long advised parents not to let their children watch
any TV until they are past their second birthday.
     Jane M. Healy, an educational psychologist in Vail, Colo. said: "Any parent who thinks a spelling
program is educational for that age is missing the whole idea of how the preschool brain grows. What
children need at that age is whole body movement, the skills of playing lots of objects and not some
difficult technology. You're not learning to read by lining up the letters in the word 'cat.' You're learning to
read by understanding language, by listening."
