17yr old and Mobile phone

[pontiouspilates]

My 17yr old DD is constantly on her phone. We pay her bill and, when she was younger, would take her phone off her at night. We have not been
monitoring her for a year or so and she is lethargic and constantly tired. Is she too old to for me to reimpose a phone curfew?

I've got the same problem, but I think they're too old at 17 to have it taken away/monitored. I'm hoping DD (also 17) evevtually self regulates!

Thanks for responding. I agree that they feel too old to have to hand them in. Its tricky to monitor stuff like how
much studying is getting done when shes squirrelled away with her phone not much judging by her predicted grades for next year Here's to a bit of self regulation!
