How do you manage bedtimes with 3 kids

[Noyesnoyesno]

Just wondering how people manage bedtimes with 3 kids. We have almost 9yr old, 6 and 4 yr old. We usually take all 3 upstairs at same time, help them get ready, get them into bed for around 8 to 8.30. Almost 9 year old allowed to stay up a bit later to read by herself. She's keen to feel all grown up (after spending time with 12 year old cousin) and wants to go to bed / stay up downstairs later. Would be a bit of a pain for us and would probably upset and annoy the younger two. Just curious how others in similar situations manage their bedtime routines.

Surely age appropriate bed times??
You are asking for sibling troubles making them all the same imo op.

We do what you do with a 12 & 9 yo. It works fine. 12 yo has been told no tv past 9pm so it mostly kills any interest and 5 mins of a news channel does the rest.

We do what works best for us it's taken a long time to get the oldest two to sleep at set times both have ASD and had trouble sleeping. We still have some rough nights but sticking to this routine seems to be working at the moment.
5 year old goes down for the night first at 9.30ish been a bit later recently cause that boy will only sleep when it's dark he's back up has soon has it's light outside.

15 year old goes to her room at 10.30 and asleep by 11.30

Finally 9 month old has his last bottle at 11.00 and wakes at 8.30

Our 9yo stays up later than her younger brothers who are 5 & 3. Could you definitely not make it work?
DH and I take turns to bath the younger 2, whichever parent isn’t on their bathtime does a puzzle / game / craft with DD for half an hour. Then we all do story time together; DD usually reads she loves this time.
Once they’re asleep DD will have a shower and then reads to us for a bit. She doesn’t have to have lights off straight away and will often read before sleep for half an hour or so after we’ve gone back downstairs.

Thanks everyone. Really useful to hear different ways of doing it. louise your routine sounds lovely. I think our eldest is keen for 1 on 1 parent time, so I think she'd love getting an extra 30 mins downstairs with a parent. She does get one of us 1 on 1 every night for story time and gets time on her own to read, but will trial something similar to what you've suggested. Thanks

I have two year gaps between my 3 so they have bedtimes that are 30minutes apart. So for example the youngest would have 7.30pm, middle 8pm and eldest 8.30pm. It was not always easy/perfect especially when the youngest two shared a room .
