I'm very glad to hear that your son had a skilled positive story. Premature babies are so tiny and it's amazing that they can be born so early and then grow up absolutely healthy if they get the right care.

The use and training of specialists is only one part of the puzzle that needs to be optimised in so many different ways. And I will point out that one of the key results of this puzzle is infant mortality statistics and the US does not score very well on that metric. I don't understand 1% of the details of why but it's quite a problem. And this is in spite of the money spent on healthcare

I don't really want to be a cheerleader for the NHS or the US system in this comment because both have so many problems involving bureaucracy, money, politics, etc. And it's a pity because ultimately it's the most vulnerable in society who are affected the most.
