Try being a grandpa (or in your case, grandma...wait, that's the name of the Cuban newspaper...
Unfortunately you're not in control of the situation, but hey, it's not your fault. It's also not your responsibility. The child will be the one innocent victim in this. You're able to form whatever relationship to the child (or not) that you wish.
However, if they're that far away, it doesn't look like it will be that much trouble. No one's going to put a sign around your neck that says 'auntie'. I wasn't an uncle until I was in my 20s, so I may not relate, but it's only family.
Just make sure you don't get saddled with diapers, sitting, and cleaning up the mess....
It's going to be ok. Eventually.
