Essential oils are powerful and need to be used judiciously. They are not necessarily, like so many YL, DoTerra, and mommy bloggers proclaim, the SAFE alternative to every medical problem out there.
Robert Tisserand is considered by many to be the go-to expert on Essential oils. That doesn't mean he claims you should use essential oils in place of proper medical advice.
Here is a list pertaining to the use of essential oils with children. It comes from his book. It might help you decide what is safe for your child. (below....sorry, it's long)
As for the irritation on her poor lip - simply gently cleaning it, let it air dry thoroughly, then keep the area covered well with a non petroleum or non petroleum wax lip balm will let her skin heal. I'd also suggest something without any unnecessary additives such as scents, colors, flavors.
For my 9 year old, I made a lotion bar with stearic acid, coconut oil, shea butter. She rubs it on any cut or skin problem she gets and finds it soothing. (I think it's the stearic acid)
Hope you fine something that works - she doesn't need that discomfort on top of everything else!
