The facts for me are that this is not my infant. And there have been no studies on the effects of vaping on a 7 month old infant.
I'm a person who believes in giving a baby EVERY POSSIBLE advantage, since they will be walking this earth for a long time.
Since I myself am working with a dermatologist, as well as an allergist/immunologist on some "issues" I'm having with vaping (and it is vaping related, but it's taken about 6 months of coordinating causes, substances, metals, and other factors to narrow down what is happening, etc.) I guess today I would say no, I would not vape around an infant given that we do not know what they may be allergic to.
That in no way suggests that vaping is dangerous to the average person, but obviously, some of us have heightened immune responses to certain things.
This is Along the Lines of my thinking.
Making a Comparison to using an e-Cigarette around a 13 or 10 or 5 Year old is Not the Same as using an e-Cigarette around a 7 Month Old. There is So Much development that occurs in the 2 Years of an Infants Life.
If it gets down to Steeping onto the Patio to use an e-Cigarette vs. vaping around an Infant. I would go with the Patio.
It just doesn't seem like Such a Sacrifice to Me. But this is Just Me.
