[GTW] Question - How to turn Hybrid Alien Baby into full Alien

My Alien Sim had a baby with Jess Sigworth (Strangerville). I went into CAS after aging her up into an infant. In her Personality section, she doesn't show the Alien icon. She has the blue-white skin of her Alien mother, but not alien eyes, and her voice seems normal too. All this suggests she's probably effectively human, and subsequently didn't inherit any powers. Basically, she just looks like she's a human who's freezing to death. I'm not okay with this. I know there's a cheat to turn a human Sim into an Alien, but my question concerning this is twofold. First off, I've heard the cheat only works on older Sims (Young Adult+?). So, is there a way to make this baby a true alien while she's still a baby? Second, will the cheat work on a hybrid at all, or do I need to remove that status first? I'm not sure how all this works on the code end, whether she's considered human or hybrid and how to push her toward full alien status.
