Marisa's reply was excellent. Another thing you might want to consider is that they may be too drying for frequent use... your child may get chapped hands. A safer way to go (in my opinion) is just to use regular wipes, and when things are really bad, put a little alcohol-based hand sanitizer on the wipe first (or just use the alcohol-dosed wipe on whatever surface it is that you're concerned about). Alcohol is a more effective sanitizer, and you don't get the resistant bugs the way you do with repeated use of triclosan and other sanitizers. However, it is drying as well. The good news is that just using a regular wipe (with nothing extra) will remove the vast majority of whatever it is you're trying to clean off. IMO, TTO and lavendar are not necessary. (FWIW, I'm a microbiologist.)
