I actually started
vaping BECAUSE of my daughter, I'm a stay at home dad and my 14 month old is too important to toss her into her playpen and leave the house for a smoke a dozen times a day.
I keep fans going to make sure the air circulates and have been planning on getting an air scrubber for the living room (where I vape the most). I stick to liquids that contain little or no VG as the few studies done seem to show that PG is far less likely to cause a reaction.
As someone who has a great deal of allergies (many have been passed onto my poor kid) I know that the fruity/ intense artificial flavors are also most likely to cause issues. I stick to a menthol vape around her and as of yet I haven't seen any kind of issues.
The BIG problem so far is that she is old enough to see me
vaping and wants to mimic it. My hardware fell unnoticed out of my pocket twice now and instantly she picks it up and mimics what I do, both times luckily she put the wrong end into her mouth and didn't seem to be trying to inhale, I'm tinking of making some kind of carry case on a lanyard to ensure this stops happening.
I suppose ALL things that are unhealthy by definition cause risks and kids tend to survive around them, we can minimize the risks and thats what is important. In your case the issues are pronounced and that means taking extra steps. It's great you are willing to do so.
I know someone with a heavily asthmatic child who lives in the downtown core of a major city and I cant imagine why she stays there. It's killing her child and she refuses to move somewhere else with out the endless smog and car exhaust because she will have to take a cut in pay or need to take on a different job. Yet she is a anti-smoking nazi and thinks that my
vaping is still killing my kid, so far I haven't pointed out the obvious in a dramatic way but I suppose we all make choices.
In your case it seems to be a necessity but perhaps a few air scrubbers and liquids that are less likely to cause a reaction might make all the difference.
