I stole the recipe from the Diaper Lotion Potion. It's awesome. Get an empty 8 oz spray bottle. Add 2 tbsp. jojoba oil and a few (8-12) drops each of lavender and tea tree oils. Fill the rest of the bottle with witch hazel. You have to shake the bottle each time you use it because the oils settle on the top. We had no diaper rash ever. And it smells lovely.
