As a grandparent I do agree to some extent with the observation that parents now have so much information that it is hard not to feel anxious. I do sympathise with how the OP feels.
But the other side of this is that there are more dangers - traffic is faster and denser - we truly were poked out of the door in the morning, either to make our way to school (in my case by public buses aged 5) or to wander the vicinity picking up friends to go to the "rec" with from a similar age.
We were not bombarded with information and there really was nowhere to look stuff up. We were given a booklet about the baby stage by the midwife and then another for toddlers by the health visitor and we just looked stuff up in that.
I do sense both a greater sense of anxiety about parenting itself and what is safe, but also about doing the "right" thing - this latter is I think fuelled by social media. Parents see what others are doing as they post about their day, and then worry that they are not doing similar. I only had the vaguest idea what my closest fellow parents were doing.
And of course I did not have to navigate/police "screens" and their sensible use. When my grandma died we were left a tiny bit of money and with it we bought a BBC computer - a thumping great thing that had no connection to anything but you could feed in tapes from which some really clunky games could be played - the children loved it!
I have seen my own AC deal with parenting anxieties that I simply did not have. Perhaps I was just a lax parent!
It is clear that parents are trying to do their best by their children and that is a huge positive - but children need relaxed parents and the anxiety that the current over-information might generate is the negative. A little knowledge can be a dangerous thing!
Good luck to all you young parents navigating these minefields ......
