Hiya Mark and a welcome to the mone forum, Pherotalk! 
Learning about the tools, what they can and can’t do, I would suggest you take a look at my sig below, Intro to Mones and How to know what are hits. Two excellent threads for you to know the strengths, limitations, and usage of mones.
Another one to know ABOUT adr is this thread:
There are threads and posts that touch on that. Basically, we don’t know what may happen. What is known is that your ‘mone’ signature with your 3 year old is formed and continues to form. Bringing in a new, enhanced or comflicting sig with a synthetic mone could cause confusion in her. NOT harm to the brain, because, these are applied topically and DO NOT enter into the blood stream which is the only way you’re getting a chemical, normally, to the brain.
Safety for you and others is important, so that is a very good question.
Use the search to get some more info on these mones and their effects on kids.
For kid friendly, I normally use the social line, such as IShine, IO and IH. I’d also use IG as it’s main ingredient is -rone. I have NOT seen any negative effects around the kids that happen to be in my mone cloud.
