Bedtime for a 11,9 & 5 year old help?

[LMC84]

Can some one help me please
What is an acceptable time for my children to go to bed
Ages 11,9 & 5
I think I put them to bed to early

11& 9 year old share a room

Need to go to bed at separate times due to fighting and arguing

But I like an early night too
As I'm an early riser

Any helps appreciated x

DD is 7. On school nights her bedtime is 8:30pm with lights out at 9pm.

Thank you

ds (11) 9.30pm bedtime
Dd (14) 10pm bedtime

My 9 year old goes to bed at 9pm. Suits us since she isn't up until 7am.

DS used to go to bed st 8 when >10. He goes to bed st 8.30 now he’s 10.

DS5 goes to bed about 730
DD is 9, an owl 🦉 unfortunately as imma lark! Goes to bed about 9 but struggles to sleep stil awake at 10-11pm sometimes!!!

Ds 11 lights out between 9 and 9.30. Depends on clubs. He has judo tonight from 7.30-9 so it’ll be 9.30. Last night nothing on so it was 9.

He has to be up at 6.40. What time do your dcs get up?

My 11 year old goes up the stairs at 7:30 and puts her light out at 8:30. She gets up at 7am.

What time do they have to get up? It's not about bedtimes but total amount of sleep. A child that has to be up at 6am will need an earlier bedtime that a child that gets up at 8am.

Ds 13 sleeps 9.30/10pm. Gets up at 7 am.

My children (8 and 10) go 8:30-9:00 ish and get up at 7:00

They board sometimes and it's lights out at 8:00 and up at 7:00. With all the giggling and chatting after lights out it's probs more like 9 by the time they go to sleep though anyway.

Nearly 7 yr old lights out 7.30 and nearly 10 lights out 8. To be fair 10 yr old could prob stretch to 8.30 but will wait a bit as I like my evenings. Both have to be woken up at 7am for school so I think sleep times are good.

DD2, 13. Lights out 9pm up 7:30am.

5yo 7pm, 9yo 8pm, 11yo 8:45pm?

Thanks everyone
All of them are up at 7:30am

I try a new routine this coming week and see how it goes

I think from what I've read it is what just suits each family isn't it
