Thank you for the story. What can i say? Wow! Dominic is probably the first cheated character that i have zero sympathy for at the moment.
Your baby is born prematurely at not...one week or two, do I hear...three, how about four, nope....six. Yet, he doesn't clock on that a baby being born at seven and a half months can have health issues. Never questioned how the child can weigh a whooping eight pounds and be perfectly healthy? No one in his family questioned this logic.
I think, it's either an open secret, he and those around him are extremely naive, or he's wants a child so desperately, that he's willing to overlook the obvious.

Fuck that job! You can get another one just tell him! You know this is wrong!
