I took a look an some data from gas chromatography on sveral brands of ejuice. There we some interesting results when you look and the indication of the data listed.
For the clouds tested, based on expected concentration of liquid (listed as "regular, low etc.), the repective percentage of nicotine present is much higher than in liquid form.
If a bottle is 36mg/mL, then its 3.6% by volume. The percentage for "regular" (likely 2.4% liquid form) is 8.5% As a weak undergrad just getting my feet wet, I would get the percentage of vaporized nicotine is higher than some or all other ingredients of e
juice solution. This "increase" in cnesentration percentage explains a number of anecdotal questions I have had for a while about dosing, absorption etc.
The point I raise here is that proximity to the little one while
vaping appears to be a bad idea. The needed information is a ratio expressing how much secondhand vapor is inhaled when the secondhand vaper is very close.
I'm no expert, but the suggestion I would make is to have your kids out of arms reach, or to not be
vaping.
