Moms now worry a ton about following all the “rules” - what “rules” did moms used to worry about?

I feel like nowadays moms (especially in the first year at least for me) are constantly worrying about so many things: screen time, organic/dye free food, blankets/bumpers in crib, coats in car seat, walkers being unsafe, the list goes on.. I know moms used to worry about silly stuff we don’t really think about too much anymore like caffeine while breastfeeding/pregnant but what else? Is this generation of moms more worrisome and did other moms have it easier in that regard to not worry about as much? Or did they worry about a lot of other things that we don’t consider now?
