Hi C.!
We go through the same thing with our 11 y/o dtr. Santa Clause gave myself my first cell phone at 37 y/o and our oldest at 16 y/o when we recognised the convenience of reaching him with sport practices finishing at diff. times, and after school needs varying... Some would argue that the waves they produce are bad for you and more research is being done here. Children are keeping them on them at all times and sleeping with them by their heads... I've found my oen son textinga about 2 am about nothing! We have him drop it off at the end of the day in the kitchen to recharge and then he is allowed to get in am. My dtrs. friend just got the newest craze phone with all the bells and whistles. We were recently at a party at her home, and I noticed she was texting more than spending time with the friends around her. I sat in Urgent Care once, and while I chatted and read to my children, I couldn't help notice another family totally plugged in and disengaged from one another. Being in health care and working with peds, I read a lot of info. that is pointing to tech. causing a disconnect from self, each other and nature/God.
Even here while I respnd to you, I recognise I am plugged in and not interacting with my family. Ha! Go figure. I think it's good to have this awareness though and find a healthy balance.
Also, I too worked at age 14 y/o and had to earn extras. Go with your instincts and don't give in b/c "everyone else has one".
Best wishes!
