I, too, do not understand the need for teens to be in contact 24/7. I have a 16-year-old DSD whose mother was insistent on her having a phone and the second month she had it she ran up a $600 phone bill, texting and talking all day long at school. can't remember exactly the # of texts, but it was insane. Being assessible all the time, I feel, it not a good thing and they never seem to have an out. Plus, in our situation, our DSD is not able to make decisions or choices, because she is always having to check with her mom about everything, thus the phone. I am not sure she is ever going to be able to make her own decisions and feel comfortable about them because of this. It has been this way her whole life, not something new.
With that being said, the text would be gone. My motto is, "If they don't hate me at some point, I am not doing my job." I don't mind making the
unpopular decisions when their safety is a concern, or if I feel they cannot handle the situation or consequences that go along with it. They may not understand, but I can bet that one day they will appreciate the decisions I have made for them.
Nix the text, nix the text, nix the text - You can do it!
