As for the baby...in the S5 premiere it would have been shown to grow rapidly,
I remember reading about that. Hate the idea. I didn't want them to get a "temporary baby" that they didn't keep/raise. Them ultimately being able to have children in the future would not compensate for that to me. Plus, I generally find the fast-aging thing to be a cop-out. There are exceptions, but generally it seems to be used in fiction as a method have the "a baby!" hook for the audience and then to quickly get rid of the baby because they don't actually want an infant/child character on the show.
