Phone issue with DD

[CURLYSANDY]

Hello - my 15 year old DD is falling asleep at the dinner table, in the bath, etc, yet I have set time limits on her phone with Screentime Labs from 10pm to 8am, yet I believe she can and is still using her phone during the night, hence her tiredness. I assume she has found a hack somewhere, but what can I do - I tried taking away her phone at 10pm and giving it back to her at 8am, but she became very aggressive, so I gave in...Help!!!

All phones are downstairs at night. No phones in bedrooms overnight. Non negotiable.

Don’t give in. Give her the option of going along with your rule or lose the phone altogether. If she is literally getting aggressive, she loses phone and all other privileges until she learns some decent manners. You are going to have to be the baddy here-she needs boundaries, not you to be her friend.

Ask her why it makes her so angry ?

Agree with Helen why does it make her angry to hand over her phone if she is sleeping? She clearly isn't.

Handing over the phone is non-negotiable. She doesn't hand it over she loses the contract altogether and you cut the wifi to her phone (you can do this to individual devices, gooole your router and how to do it). Also in this house, you hand the phone over with any attitude and you lose it for several days.
