What exactly would happen if someone wore something like Turn Up The Heat around children? Also what other Pheros should you avoid using while around children. This is a potential concern to me because I like to play with my little cousins etc and I could see myself forgetting that I have this stuff on and doing that. So what exactly could happen 
This has been discussed as length and a quick search will give you a lot of the original discusssions.
The bottom line is that most pheros will affect children but will not cause any harm. But they will have the effect you would normally expect to see with that phero, and possibly even more so given the lack of social filters and to some extent self-control that kids have. For example wearing Io around kids could make them even more talkative than an adult would be around the same dosage.
The one exception to this is 'none. A lot of experienced users feel that it is best to not wear 'none around kids for a variety of reasons.
My testing of none around children is that it makes them misbehave. Run around. Talk back to their parents. Disobey them and the like.
i’m working in an elementary school for a while. this morning i was using a314 (one drop to my jawline) and 2 sprays of IS 2x (applied to my neck).
maybe two hours after application, a bunch of children entered library, where i was at the moment sitting in front of a computer.
they were pretty quiet when they came in, and as approaching me, they started talking all at once and they started wondering which game i was playing (there were no games in the pc). they were talking too much and some very silly things, yet again they made no troubles. they also became very cheerful and started running around me in joy.
once the bell rang (couple of minutes later), they had no problems leaving me (they were not sticking to me), so they ran out of the library, which made me think pheros had some obvious effects on them…
I have two little girls 5 and 2 when I am wearing phero’s of any kind all they wanna do is hug me, and thats good but they dont let go! they get all snuggly lol
