My daughter goes to sleep at around 4am, wakes up at 7am, does her day at school, comes home at 3:30pm and then sleeps until 8pm and does it all over again.
I've suggested I remove her laptop/phone to which she laughs and asks me what the problem is?
I know she is getting older but she is still only 16 and at school.
She is a good student and does spend the time to revise for her exams, with a little bit of Netflix but honestly, I feel like an awful parent!
