My daughter who is 13 has a smart phone (HTC Imagio) - so to answer your question - I did. Does she truly use the features of the smart phone - no. Does she surf the web on it - a bit but not much. She uses it more for facebook, texting, listening to music and calling friends & family. Can I see where it could lead to problems - yes - but as it has been indicated in this thread and others - they have more access to the internet than we did at their age whether it be in our homes, a friends house, the library, etc. We have regular discussions about what is right and what is wrong and do I expect there to be mistakes made - yeah (heck I know adults who possibly should not own a smartphone)....but if something of value is learned, it becomes a life lesson. I can safely say that my daughter understands there are consequences to wrong actions and she also understands prohibited sites on the internet. We talk quite often - the phone was a replacement to me (LOL) and she has told me both times someone she did not know wanted to add her as a friend in FB. Altho my daughter is very tech savvy, she does not delete the history in her browser - so I can review it when I wish and she knows that I would question any strange sites. I will finish my post in saying - trusting your kids and showing them responsibility can never start when they are too young...As my daughter gets older, I might have to edit my post (LOL) but I would not regret my action of allowing her a smartphone at this age.
Well done, and well said.
