Well I dunno; I smoked cigarettes when *I* was pregnant, and my son didn't come out with 3 eyes or anything, and no lung issues, and not the slightest bit premature (as all the scare stories would have it). I did find that smoking in the house with him gave him bronchitis, so I had to take it outdoors; vaping doesn't seem to cause anyone any problems -- anyone currently breathing air, that is. The unborn? Who knows? Nowadays, I'd probably be inclined to err on the side of caution, because if there is the SLIGHTEST thing wrong with the child, and you have vaped around his mom while he was inside, you'll blame yourself, so.. yeah, caution wouldn't hurt at all. I dunno if going outdoors is strictly necessary, but maybe in a different room. It dissipates very rapidly, so if she's just not around you while you're vaping, it should be fine. The only possible caveat I can think of is that nicotine constricts blood vessels, same as caffeine -- I did abstain from caffeine for just that reason while pregnant. I dunno if she could be exposed to any significant amount of nicotine from the 2nd hand vapor, but any constriction of blood vessels for the pregnant/unborn would be a bad thing.
