I use the brand Plant Therapy. I use the oils that are labeled "Kid Safe" for most of the scents. The scents that are not labeled "Kid Safe" areEucalyptus, Lime, Peppermint, Pine, Pumpkin Pie and Vanilla.
(If I am out of this brand, I will ocassionally use the Sprouts brand "NOW")
Just a reminder even if the oils aren't labeled "KidSafe" does not mean that the other oils are unsafe. Plant Therapy has high-quality oils. If you would like more information here is a link!
