Teenager wants her freedom

What you have asked for seems reasonable but it does depend on how often you demand the updates and when you start to worry unduly. The only way forward is for you both to talk about it and agree a code of conduct. Perhaps ask for contact numbers of her friends – which you have to promise you’ll never use except in a dire emergency. It can be difficult for mothers to let go and allow their teenage daughters more freedom. Stress to her that if she wants more freedom, then the price is keeping you worry-free.
