I think a lot about this too.
My parents - probably in the style of many 70's parents - were quite selfish.
They loved me, but being 'parents' wasn't time consuming or something that they worried over.
There were no grand holiday plans, in fact we never did anything much in the holidays.
We had occasional days out but they were very occasional. Worrying about my amusement just wasn't a factor. They just carried on as normal and went to work. I was on my own (an only child) a LOT. Childcare? Er..nope
Nothing was geared around me. No 'playdates', they weren't expected to help at school as we are, no special birthday parties and I walked miles to and from school from a very young age. No help with homework either.
As I say I was an only child and when I see all the angst on here about that and how a child might feel about it, I do have to smile, cos again my parents never let any such thought cross their minds.
At the time it all seemed fairly ok. Well maybe, I suppose. I think to some extent we may as a society have gone too far the other way today. BUT - I do feel my parents should have tried a bit more, and in retrospect I feel quite resentful on behalf of my younger self, who I think was in fact quite a lonely little girl.
My parents wanted a lovely house and by god everything in terms of time and money was sacrificed to achieve that aim. I think they went too far with that goal and so I try (with lovely dh) to do things differently.
I do much more for my own dc. I want them to have happy memories of their childhood and to feel they were really wanted.
It has to be balanced though in terms of making them into nice people - I hate spoiled kids who are handed everything on a plate. In terms of material things they don't have nearly as much as their peers, but they appreciate what they do have.
In terms of attention though, I don't feel there should ever be a finite amount of that because I really wish I'd had more of it when I was growing up.
I do think many children do have too many planned activities. They don't get the free time they crave just to play, mess about and to dream. Those moments are very important. There seems to be a worry that children left to their own devices and not at 'an activity' of some sort reflects badly on a parent. I don't think it does at all, provided the parents are interested.
It's funny though because my parents now they are grandparents seem quite bemused at our level of commitment. I think it probably throws up their own parenting into stark relief but, typical of my mother , she seems unfazed and is quite adept at re-writing little bits of history in her head and convicing herself that they did then what we do now. It's utter tosh of course, but there's nothing to be gained in pointing that out to her other than falling out over it.
