I had Wolfgang Munch just go up to Vlad in his home and just ask to be turned, and then while he was still in the process (not yet complete) he and Luna Villareal (who wasn't a vampire at the time) tried for a baby and conceived, and that one got the vampire symbol above the traits, in CAS once it was a toddler. Then they tried for a baby after he was fully turned, and that one also got the symbol once it was a toddler.
Fun parental interaction: Wolfgang was able to give the toddler a "batwing ride" by picking the toddler up, then turning to bat form and flying around, then rematerializing with toddler still in arms, which appeared to be a lot of fun for them both. And he also is able to give little lectures on vampire life and history to his vampire kids once they are gradeschool rather than toddlers.
It also seems insanely easy to become a Master.
