I have night owls. Fortunately for much of the primary school years I could get them up at 8am, fed a good breakfast and walk the 5-10 mins to school within an hour.
Some children are early larks, and that's fine. What I do find is that some people get very moralistic over bedtimes, particularly early ones or convoluted, time consuming bedtime routines.
DM annoyingly has it in her head that because I haven't forced my children unwillingly to bed at the golden hour of 7pm, that they have no bedtime routine at all and that I am therefore a terrible mother. No amount of correcting that ever sinks in.
The reality of her ridiculously early, arbitary bedtimes so she could have her Adult Time was a general reluctance to go to bed and a battle, then lying there awake listening to the theme tunes of The Bill, then Van der Valk or other 9pm dramas playing in and out while I was bored in a darkened room for hours. In the summer with a couple of hours of daylight, it wasn't so bad to get away with trying to read, but in winter there'd be a telling off for trying to read by streetlight or crack of light by the door, and dire warnings about the health of my eyesight would be given.
I work with my children's body clocks combined with the reality of routine. There is a tech off, upstairs winding down time. DS (10) has a lights off time. That's fizzling off for autistic DS (12) as long as he's doing something restful.
7pm never worked for us. When they were little and at nursery, we weren't home before 6pm. With no baby sitters, not being tired until 8pm meant that it was viable to go out to somewhere like Morrisons Cafe for a night out together and do food shopping after work and spend time together.
Time just rubbing along together is valuable and often more so than Quality Time. Hanging around the kitchen meant I learned how to cook without being taught. Hanging around my dad gardening meant I learned a lot about the garden and nature. Being together is valuable. That feeds back into bedtimes, as we generally try to eat together as a family as that's a good time to all catch up together. I never wanted to do split service dinners especially if it involves multiple dinners (as some meals keep better than others)
