My daughter, also 14, has had a phone for a couple of years now. It was a regular flip phone and while it did have texting, you had to pay extra for it. She used it sparingly and proved very responsible. She has a friend that whenever she went out with us would text constantly..even during dinner. Both Sam and I felt this was very rude. Obviously we were not a priority. Sam and I talked about it and both agreed that she would never do that. When it was time to get Sam a new phone, we chose one with a qwerty keyboard for easy texting. I also allowed her to have unlimited texting since she proved responsible with her other phone. When she goes up to bed at night she turns her phone off and charges it. Of course she turns it on first thing in the morning and usually has a text or two but it's not like it's that important...Sup? Hey? that kind of stuff. She very good at discerning when and when not to text. I don't have any complaints...most of the time. She wouldn't dream of texting during church. I know I have a very compliant child and it's not always as easy for others. I don't think you are being unreasonable at all! If I find out Sam isn't keeping hers turned off, I will do the same. I used to take her ipod away when grades slipped or when I needed some sort of leverage....now it's the cell phone...her baby. It kills them if they can't stay connected with their friends. Oh, she also knows that if I'm paying the bill that I can pick up her phone at any time and read texts, ingoing/outgoing calls etc.. she's cool with that. Not that she loves the idea but knows I would be doing it to protect her.
Perfect!!!
