There is an misguided tendency in my mind to just say- get her a flip phone- after all that's what we did for our boys.

BUT, I used to carpool a group of kids to the the pool for 30 minutes every day. This typically included 3 12-14 year old girls who seemed to forget I had ears during the trip. Let me just say that there is NOTHING on earth meaner than many 12-14 year old girls. The social warfare that went on- all with phones as a main tool- was unbelievable. The minefield of tween aged girl social life is completely unfathomable to me. I wish you good luck.
