The idea of owning a cell phone appeals to most kids, especially tweens, who are forming social groups and getting involved in after-school activities. But how do you know when it's time to let them phone home with their very own phone? The first thing to investigate is whether or not their school allows phones at all. Since catastrophic events like Columbine and 9/11, many schools have relaxed rules about having phones. But it's worthwhile to check first - and be sure your child is capable of understanding and following those regulations. Analyze whether your child really needs a cell phone - most preteens don't. But it might be a consideration if your child is involved with a lot of extracurricular activities that end at variable times. When they need a ride home, it's easier to reach you when they don't have to search for a phone.
