I am 58, with daughters of 27/30. Oldest is pregnant.
Back when I was pregnant in the mid/late 70s they didn't do ultrasound unless needed. Today it is routine. I even asked the Dr. about using sugar substitutes and diet drinks and this was ok. Today it is suggested/stongly preferred not unless diabetic. Coffee is now on the forbidden list. I always was a coffee drinker. We did not have/use anti-bacterial soap and cleaning agents, regular was fine (which is suggesed again today). And the list goes on and on.
