My advice is not to progress to Mayor event right away and knock out all shelter and surface pregnancy events namely Angela, Kira, Melisa, and Tiffany. The reason why is to focus on finishing there content and not miss any pregnant sex scenes while grinding for cans and optimizing your time so you have to constantly look over your shoulder making sure you didn't miss a sex scene. Then all the remaining is content is then at the settlement. That includes the Android as she can only create your child after the Armory event. There is no child event for the Android CR route yet.
