You can also make a gum paste by combining the oils into 5 teaspoons of un-fractionated coconut oil (the harder one) and combining and rubbing gently onto sore gums.
A note about using Thieves Oil. Please only ever use Young Living Thieves Oil on your little ones. Every other knock off version of Thieves Oil is made with Eucalyptus Globulus and is not safe for children or animals. The authentic original Thieves Oil from Young Living is the only one that contains Eucalyptus Radiata, which is safe for children.
