Aspergers

So my mom has 6 siblings, 2 have mild to severe aspergers/autism. Neither my moms parents nor siblings did. One sister (without symptoms) had 2 sons (no symptoms) and one son had a daughter (with a woman who did drugs the entire pregnancy) who has autism. My mom had 4 children and I think one of my brothers has aspergers (undiagnosed). All others had children without aspergers.

My boyfriends father has mild/moderate aspergers as does his brother. My bf is socially anxious and hates confrontation but is also very social. He’s an introverted extrovert, I don’t think he has it.

What are the chances that our baby will get it?
