Devil's Advocate here:
It is a bit odd that skin color is mentioned. I do question the use of skin color for these two characters specifically, because it is mentioned nowhere else in the module. None of the people from Morgansfort have skin color mentioned, so it strikes me as odd that the detail was added specifically for these two NPCs. Freudian slip maybe? If you were trying to showcase a specific part of Glain (i.e. the southern tribes), then more details should be provided about individuals from that part of the world rather than skin/eye color.
I've never particularly liked having pregnant anything in my game. It's a game, so I keep it "gamey"...not a "simulation" of fantasy world so I can get my players to question their specific PC's moral quandaries. That's me. That's how I roll. Some other people like having the PCs struggle over killing baby goblins...but I don't get my rocks off that way. I never have. Never will.
As such, any module that has "pregnant anything" automatically gets adjusted so that's it's not pregnant...except maybe the local fauna. There are no humanoid "children" in my games...there are "young"...but no "children". "Young" orcs attack your calves with sharp knives and rocks...better hope your greaves are up to snuff!
