My older dds are in Year 9 and Year 11. Yesterday Year 9 dd got in from school around 4pm. She started her homework at nearly 9pm 
I was in and out the house with my other dc in the afternoon but as far as I could see dd2 was watching tv, on her phone and generally messing around.
Dd1 who is in her GCSE year is also spending too much time on her phone. Dh and I are thinking that if the phone is such a distraction then we should intervene and set some limits.
So we are thinking of saying that they are allowed one hour of phone time from when they come in from school then they can have it back when homework and any other chores are done.
AIBU?
