It’s fine.
You know your children better than a bunch of strangers online.
My DD is ridiculously sensible and Covid19 matured her even more to be self sufficient and be on her own in the house (whilst both parents worked within the home but tied up in long online meetings for hours on end)
When covid was over she was 10 years old and was regularly left on her own. Some people have an opinion on that but I’m of the view that I know my child. I have assessed the risks and have taught her things to do / not do and what she could do if a situation happened.
I never leave her on her own if shes uncomfortable (she doesn’t like night time, eg I offered to pick a friend up from her works do to save taxi cost, but dd didn’t want to be on her own asleep, which is of course fair enough).
