Here's Liz Atwood with this week's Tween Tuesday:

Do your kids look at you when you talk with them? With all the cell phones, iPods, computers and other digital devices, it seems to get harder to get kids' attention. My older son nearly always has the cell phone in one hand and the iPod in the other. The younger is glued to the laptop playing games.

But researchers at Stanford University found that tween girls who spend a lot of time watching videos and using online communication may feel less social success, sleep less and have less desirable friends. On the other hand, kids who spent more time in face-to-face communication seemed to have greater social success, greater feelings of normalcy and more sleep.
