I would say crespelle. But even those are made with more eggs. Usually the version similar to OP’s I make them with milk and flour + a single egg, so they are lighter.

Don’t you also have налистники? Or is that just some specific “type” of блин?

I have eaten оладьи, even though I was not aware they were called like that, and they were made with kefir/expired milk, right?

I think it’s similar in Czech, and in our (Italian) family, my mother’s side is Austrian and “palacinken” (some italianized german word) has been a family dish forever.

Why are you assuming that the female relative is a “need” in order to empathize and not just a way to feel closer to the problem? I think it’s fair that if you have deep connections with someone, their problems become your problems. It doesn’t mean you wouldn’t care about that if you didn’t have that connection.
