I would really like to see Rick walk out there with baby Gracie and have it be like that one scene from "Children of Men". Doubt it would happen, though. I'm guessing her mother has died - If my baby was there, I'd be in the room with her, especially since I guess Dad was the one Rick killed. I wonder if the Saviors would retaliate heavily for the taking of Gracie, though it would be a tough spot to be in because you can't exactly leave a baby alone in a building full of possibly reanimated dead guys.
I really, really need to know what happened to that baby and I am 98% sure that we won't find out.
I didn't think of this, but you may be right! Plus, Negan has shown a semi-soft spot for the kiddos, IMO, so if she was his baby, he'd definitely want her nearby. Might be why he was enthralled with Judith as well during the spaghetti scenes. And furthermore, he has all of those wives. We saw Sherry take a pregnancy test. There's definitely a possibility he has at least one baby. As far as I saw, though, she was the only one around.
