Well... When it comes to off-screen events, I only mention them if they are important, and only in story notes. I've chosen to leave the fight between Rumple and Cora, out of it, since it is not clear what exactly happened between the two of them. This is what is said in "Into the Deep":

Regina: "Apparently, you taught her well. (...) she's on her way. And I don't think I need to remind you, how most unpleasant that would be for both of us." Mr. Gold: "For you. I can handle Cora." Regina: "That's not how she tells the story." Mr. Gold: "I won in the end."

It could easily refer to a battle of wills, or something that took place over several years. Either way, it is not very clear.

As for the other: Rumple does say that he held Regina as a baby, but I don't think that's important enough to mention. However, I do not think it's a plothole. Yeah, Cora and Rumple broke up, but that does not have to mean that they didn't see each other again. Or Rumple could have just teleported into Xavier's castle when no one was looking, and picked up the baby.
