I've read it all now and I am fuming more. Agree with the 'woe is me' sentiment that runs through it.
"They began the IVF process but faced challenges along the way – hearing the news of a successful pregnancy on the third attempt."
They began the IVF process? I'd say it was the woman who did the work here - 3 times, before they got a positive result. And how many embryos did they transfer if they were wondering if there were more than 2 in there, maybe even 4 or 5?
And on top of taking the twins away from their mother at the point of birth, the babies didn't even get to sleep beside each other, so worried about each of the babies bonding equally with each dad. they couldn't even put the babies needs before their own once they had them home. Very sad. 
I also wonder how the daughter will feel once she is a teenager and knows that she had a perfectly capable mother but was never allowed to know her. Or when she is an adult and carrying a baby herself and realises it is much more a phenomenal process than say growing and hatching a baby chick in an incubator.
