Thinking back to when I had my kids in the 70's compared to now. The hospital was archaic! My second born was thought to have a major problem that x rays showed. Bad bad problem. Ultrasound was brand new and only one hospital in the state had the machine. I had to travel there to get the ultrasound. It showed the baby was okay! But the old Drs. said they didn't believe in ultrasound and prepared me for the worst. Two wanted me to not have the child!! My DD was born healthy and I went through mental agony for four months and fighting the Drs and being told I was foolish, selfish, and ignorant, for believing in ultrasound when the x rays showed the problem.
