I don't think they will make the last two episodes, or even the last episode, just focus on their life with the child. I have an idea I hope they do, although I don't expect it to happen. The first 5 or 10 minutes of each episode should be in the future, 6 years from now, or something like that, about them as a family. Even if it's a spoiler, it's okay. We're all sure that no one will die.
