The three organic essential oils in this blend are calming and gentle, and are the only oils that we would advise using with children between the ages of 2 and 5. (We do not advise using any essential oils directly on babies before the age of 2-See our Hydrosol Spray for Babies instead!) The oils are Lavender, Cedar and Orange. These oils are at 5% in a carrier oil of our choice. The container is glass, and should always be used with adult supervision. The oils can be directly applied to the skin, or sniffed for the aromatic benefits.
