I was born in the 60s. The way my parents raised me wasn't neglectful. They themselves were raised in a time when the world was a lot safer, so allowing us out to play young and out of sight was normal. My family lived in a cul-de-sac and at age 5/6 it was normal to play just out of sight of the house window (but still within the close). Me and my brother would often go and play in the local quarry when we were about 10/12, about 20mins walk from home, and parents just knew we were 'out playing'. We didn't have mobile phones then, so no way to contact us either. It was simply "be back by the time the street lights go on".
It was a different world. We didn't have bicycle helmets, but didn't all die from brain injuries. Cars didn't always have seatbelts, or they weren't mandatory, and we survived, without having to sit in a car seat until we're 30, but then there was less traffic and people were not such mad drivers. We ate good, home cooked meals, rarely had takeaways, over processed food or junk food. We survived and were healthier for it. Our parents interacted with us, rather than being distracted by their mobile phones. Yes, we got the occasional light smack, but it didn't damage us and we respected our parents as the smack meant we'd gone too far. We were allowed to learn by assessing risks and making mistakes, as well as being instructed and taught life's lessons. We also didn't live in as sterile a world. We played in the mud and drank from the hosepipe, our parents didn't sanitise surfaces to death, so we built up a good resistance to germs. Best of all, we didn't have social media, with photoshop and unrealistic ideals of looks and body shape, or constantly being told what fashion/brand/logo we had to wear, so we grew up with confidence and much less anxiety than todays kids. We weren't neglected, we simply lived within the laws and constraints of that particular time.
Theres lots about today's world that's great, but I'm personally glad I grew up as a child of the 60s, and not the over-cautious, over-sterile, over-processed, over-woke world that we have now.
