My son Elliot was one in a million.

What are the odds of having identical twins? About 3 in a 1000.
How many of those babies have growth problems? Less than half.
How many of those also have heart problems? A tiny proportion.
How many of those develop NEC and die at eleven days?

One in a million.

And how many have an identical twin who is perfectly well?
