@SommerTen My mum (as well as having been a children’s social worker as I mentioned upthread) had also been sexually assaulted several times as a girl - aged 10, 12 and 14 and so on. So she was very very cautious about the possibility of strange men. I was not allowed to “play out” (as other kids were from a very young age), and she was very clear about warning us what to do if a strange man approached us, asked us to look at some puppies, offered sweets etc.
(She also very much did not leave us alone with any male relatives, eg uncles etc., no matter how much she trusted them - I think she had seen too much in her social worker days to take any chances with anyone.)
We were allowed to play on the field nearby from about 8-ish but only for a couple of hours at a time (and I was a v v sensible child - my siblings weren’t allowed to unless I was there). I was not allowed to walk to school alone until I was ten and in the last year of primary school (and the school was five minutes’ walk away with no road crossings). I went to school alone on a bus from year 7 but was not allowed to go into the town centre alone with friends until 13 or so.
That seems pretty much the same as today’s kids are allowed (DD’s school does not allow children to arrive/leave unaccompanied before year 6).
I was left alone at home supervising younger siblings for short periods of time from about 12, and by 15 was taking them on long journeys across London etc. and babysitting for my parents’ friends. However I was considered a very sensible child/teenager, and my siblings (who weren’t!) were not left in charge of anyone until much later - very late teens or so!
We also always had car seats, sun cream, mum was a crunchy knit your own muesli type about healthy low salt food, etc. etc. Not really much different to today.
I do think there were large variances during the 80s, though - both depending on where you lived (eg in a city or a more rural community) and across different social classes and communities. My parents were very middle class despite both having grown up in poorer working-class communities. They were a lot more cautious and suspicious about child safety partly because they had both been left pretty much free range in their own childhoods and had seen some stuff…but also they no longer lived where they had grown up, so they didn’t have a local community around that they knew, to rely on to all look out collectively for small children. (eg. where we grew up was a very nice suburb, but with mainly older people, not many young children, and not many people around during the day, which I think makes a big difference to how much you’d let your children out without direct supervision.)
