I think infant mortality rates might actually increase. The US has more pre-term births than many other countries, and we have a lower mortality rate than most European countries for babies born before 37 weeks.

The argument is that preterm births are the cause of our higher infant mortality rate, and these can be avoided by improved prenatal care.

They may or may not. But I wonder if any cuts will be made to how preterm babies are cared for. I remember finding the blog of a woman who gave birth at 25 weeks while on vacation in FL. She was thanking her lucky stars that she went to one hospital's ER over another one, because the other hospital had a non-intervention clause/rule if the baby was born before 26 weeks. Luckily the hospital she went to didn't....and he received all the medical care he needed. And fast forward a few years later, he had no deficiencies at all, no hearing issues, no sight issues, no internal issues. Nada. But the other hospital wouldn't have tried to keep him alive. Crazy.

There will be some rules made, and I doubt it will be a carte blanche to do whatever is necessary.
