Has anyone had any experience of their GC needing lot of sleep of did their children, when teenagers need lot of sleep ?

Goodness me, yes. Teens can turn sleeping into an Olympic sport. Curiously though, a message asking if they want to meet XYZ at SuchandSuch Place can have them leaping out of their beds in moments!

Teenagers actually need almost as much sleep as young children, and they often experience delayed sleep phase (meaning they're up half the night and then sleep until noon). All of this is physiologically and developmentally normal.

Is he fine in himself? Eats well, does well at school, sees his friends? If all of these things are fine, it's probably not a major issue.

My parents used to have a rule at the weekends and during the summer. You had to put in an appearance for lunch. (Assuming you weren't working.) Breakfast was optional.

Yes, good points Esspee.

Thank you.

Could it be boredom, poor health or just laziness?

Ohhh thank you Smileless2012

I will tell my DD these replies.

Thank you ....

No experience of GC but both our boys could sleep for England when they were teenagers and it's very common.

Ohhhh sorry, he is 14 years old.

Thank you for your posts.

You don't say his age; but teenagers do sleep a lot. It seems a switch goes on when they turn 13.

It could also be post-covid if he had it, or school stress.

Teenagers have a reputation for being able to sleep almost round the clock. Mine never did because when not at school they had a full calendar of sporting events, their choice.
