But isn't learning how to get up in the morning a part of growing up...? (Same with going to bed on time) Couldn't it be taught just like cooking their own food and grooming themselves? I learned pretty quickly the consequences of tardiness by getting detention, lower grades, etc. Now - if they don't care one damn about school then I think that's a separate problem and them avoiding school by sleeping in is just highlighting a separate problem. If they have a really hard time getting up every morning and can't sleep at night then they could have insomnia and do well with at least some acknowledgement of it. I suffered with insomnia for over a decade. It was due to horrible amounts of stress.

Back to you: If they're always expecting their parents to wake them up every morning - how are they going to fare when (if?) they move out?

I was just like the kids the op described. Turns out, I never could make it to early college classes (so I got Cs in anything pre 9AM). I quickly learned to only sign up for later classes. Then, I entered the workforce as a software engineer, working for companies where I could head in late. Life’s worked out ok for me.

Turns out, you can live a perfectly happy life in which others don’t dictate your morning routine.

yes, middle schooler and more so high-schoolers should be responsible enough to get up in the morning and be ready by themselves.

My kids are 5y and 3y, and the oldest has just started kindergarten. I'll wake them up if need be, and then if they're ready for breakfast on time they each get a penny. Boy do they want that penny!

With older kids I would imagine some sort of just "here's an alarm clock, getting up and ready for school is your job" would work, but I've never been a parent of older kids ;)
