I was going to start a thread about this!
The funniest and weirdest thing I think about was people selling actual cat nets because people so often left their babies in prams out in the garden to sleep/scream.
The hilarity of cat nets aside, parenting sounds pretty easy if you ignore (or can't hear) your baby screaming so don't worry about nap times in the crib. Also if you just shove your kids in their bedroom and ignore their crying when they misbehave, feed them formula rather than breastfeeding (so, so much easier) and have no concerns about them being out in the street/park etc all hours because "it was a gentler time".
See, most of the above would be considered neglect these days. It really annoys me when older people complain about how anxious mothers are now and talk about how they just got on with it. Thing is, we now have 60 years of studies (and therapists bills) to show what's been wrong with their parenting style so of course we're anxious to avoid those mistakes (or for our charmingly free-wheeling kids to get stuck down wells etc).
On the other hand, I do acknowledge that those parents (but if we're being realistic, it's mothers) had a whole other world of stuff to deal with. I could never give my kids the attention I feel they need if I was supposed to have an immaculate home with perfectly turned out kids in white, home-made clothes, dinner on the table for the man while looking gorgeous.
Too much Bewitched? Perhaps. Was weird though when MIL was ironing all our tea towels. I said, we just fold them and put them in the cupboard. She said no one will be able to say she has untidy tea towels in her cupboard.
See also taking the mostly empty bin bags out 3 times a day because it "looks better". And oh the shock of her son changing nappies, carrying crying babies around, bathing them and all!
We have it pretty good these days. I also think we have much more acceptance of children (older posters please correct me if I'm wrong). I have older relatives who are/were a bit "children should be seen and not heard) but I find most cafes, museums etc are very welcoming to children (and their noisy fun) these days. Were there many cafes with sandpits in the 70s? I think it might be a bit of a golden age for the little tykes.
God, what a long post! I'd rather parent now. At all costs. But please give anxious new mums a break. We have a lot to be anxious about. I can point you to the studies that prove it!
*please no one take offense at the above claims of neglect. I'm stereotyping to make a point.
