Yes a few of my kids class mates ( grad 3 to 5 ) have been getting smartphones and my kids are wondering why they cant have one too, as I mandated the rule that no child of mine gets a smartphone until they start their first year of high school.
I run a pretty tight leash on the availability to, devices, laptops and their PS/XBox during the school week, as they have, art, tennis, piano classes, swimming squad and homework taking up most of the after school free time and I allow them to let their hair down on the weekends.
I don't find that they need a smart phone as yet and try pretty hard to keep my kids active with 'other' activities to keep them motivated etc.
So when did you allow your children full access to a social media equipped smartphone?
