Spoiler:Isn't that baby supposed to drive some of the plot? Doesn't Melisandre use the newborn for a sacrifice?
Spoiler:The baby is important in the book for reasons you state. Jon switches Gilly's son and Rayder's son and Gilly is sent away with Mance's son to ensure he is not killed. This particular plot point seems easily changed though IMO but we'll see if it comes up. The first 'king' burning plot was changed in a previous season when Gendry showed up at Dragonstone instead of the other bastard son being the target that Davos sent away, sooooo it leads me to think the whole plot point with Rayder's son just may not happen.
