Second hand vape

I get nervous to bring my 3 month old out to any gatherings with “friends”. For example my friend is having a house warming party at her new (small) apartment. I know there will be a lot of people there and it’s likely that one or more of them will vape while inside. I don’t mean openly, obviously vaping.. just discretely taking hits of their pen here and there. If I see it, I could say something.. but often times people can do it without you even realizing.

I avoided indoor gatherings like this when pregnant for fear of second hand vape and now that my baby is born, I’m wondering if I should still be avoiding it? On the other hand I can’t never leave the house with my baby. What would you guys do? Anyone have insight as to how vaping works and how bad second hand vape is?
