This inhaler contains organic Lavender, Orange and Cedar essential oils in a safe, plastic container. Children often find these to be very calming and relaxing. And while these three oils are considered to be safe for children over the age of 2 years, they should always be used with adult supervision. We do not recommend using essential oils with children under the age of 2 years. We recommend the use of Hydrosol Waters instead. (Please see our Pure & Simple Calendula Lavender Hydrosol with Aloe.)
