I'm 99% sure the pup in the graveyard was a Church Grim.

In older times, churches always hosted graveyards. It was thought that the first being to be buried in the graveyard would have their soul bound to the place, and become its guardian. Thus, the inaugural burial was almost always for a dog that was a good guard dog in life. They're known as Church Grims.

I mean, he has one inescapable consequence; he has to live with himself.

If something changes and he's suddenly thrown back into the normal timeflow after years and years of doing whatever he wants with no consequence, he's gonna have one fuck of a crisis about identity and values as he tries to pretend he's the same person and slip back into his life.

I'd be shocked if you haven't tried convincing your wife of the truth yet--y'know, telling her that you're in a time loop, and using knowledge of the previous versions of the conversation to say what she's gonna say before she says it, that type of thing.

What happened when you tried?

Have you ever considered--once you convince your wife of what's happening--inducing labor at home, as early in the day as you can manage, and then going to the hospital?

I have no idea how you'd go about the induction, but you have infinite time and all the information on the internet at hand, I'm sure you can learn how to do it as safely as possible.

Best of luck.
