That reminds me of something, Joolyjooly...When I was PG, I read the book, The Continuum Concept and it was all about letting children just 'be' and letting them watch us adults getting on with normal life, work etc, rather than focusing on them at all. This made sense to me (although other parts of this book don't resonate with me).
However, there are several factors that don't allow for this - a complete lack of a 'tribe' around us is one. We have no family who we see regularly (sis and bro and their families don't really have interest in meeting up ever...parents dead...no ex or his relatives at all).
All the twins' friends live in disparate areas and also each twin has the sort of friends who are completely incompatible with the other twin and friends. So having a bunch of children round doesn't work at all, or even two others!
So it's always (except by special arrangements for playdates etc) just me and the twins alone.
Secondly, there's nowhere safe for my DCs to play outside the garden/ home cos of the busy road. Once or twice, they were 'invited' to play in what's actually a privately owned field backing onto our garden, by trespassing gangs of children. However, it was just a ploy to have some victims to bully - as the other children go to the same school (not my twins' one) and are a closeknit gang and were absolutely horrible to the twins.
Since then the field owner has forbidden trespassing - which we're glad about and I never liked the twins to trespass anyway. The gangs still roam there and call out rudely over our fence and stare but we try to ignore them.
In my home neighbourhood, as a child, there was a cul de sac nearby where lots of the local children played and some woods behind that too. We were bullied by some but OK with others - as there were sufficient kids to make a big enough mix. However, we three mostly played with each other anyway, roaming far and wide to the woods, the park etc.
So lack of a safe free environment and a good 'tribe' of mixed aged children is a big difference for my DCs.
Here is where I confess that, unless I stop them proactively, the twins will often spend most of the day, on and off, at PC or screens, doing a variety of activities - but all on screen . Not every day of course but on a typical school day, PCs go on from 6.30am till 7.30am (when we leave for school. Back on again for about 2 to 3 hrs at night. At w/es it may be up to 6 hrs on and off all day and is the default activity they return to on coming home from anything else, on waking, before bedtime etc etc.
I attempted, feebly, restricting screen time to 2 hrs a day. It was Hell! for all of us. They fought, were bored, hung around me, provoked me. I also have tried restricting it to early in day and late in day with a long several hrs break inbetween. But then I can't get any space to do even the most basic domestic tasks, like cook a meal, clear the kitchen, do laundry etc.
The one thing of course that stops PC time is me taking them out or me playing with them. But I can't do this all the time and so that's why I need to find ways of making non-screen activties, carried out independent of me, very attractive.
DS1 would quite happily do other stuff alone for a bit, provided it was 'risky/ dangerous' but of course there's a limit to what I'd let him do at this age. DS2 is more risk averse and if they won't do something together then DS1 comes back to me for company...
Like you, Mila mae, my sister, brother and I played lots of interactive imaginary games together, made up gangs as a threesome, codes, languages....but my twins, as I said before, are so incompatible. they'll do this for a little bit but Asps-like DS2 HAS to be in charge/ in control or he won't play and DS1 wants to do things, understandably, in a more ordinary way, as he might with a more typical peer. So it just doesn't work for long enough.
Further suggestions please of attractive activities for almost 9 yr olds to do alone???
