First you need to infuse your oil with calendula. Put a handful of calendula flowers in a jar with 16 oz of the oil. Let this sit in a sunny window sill for 2-3 months. If you don't want to mess with this or don't have time, just buy calendula oil.
Calendula is an anti-inflamitory herb and is great for skin problems such as diaper rash and eczema.
After you have your infused calendula oil, strain out the flowers, pressing all of the oil out of them, remove the calendula, saving only the oil. Mix this infused oil with the 16 oz of castile soap. This will now be your "concentrate", which you will use repeatedly to make your solution.
To make your solution, mix 1 cup of water with 2-4 Tbsp of this concentrate. Then, use this with your cloth wipes. You can wet your cloth wipes with this solution or use it in a spray bottle on your baby's bottom.
This solution, with cloth wipes, is superior to wet wipes you can buy in the store. It is silkier and gets their skin cleaner than store-bought. I am a busy mother of three children and I still feel this is one of those things that is worth the extra time and effort (Thanks to my friend Lydia for this recipe).
I made my own cloth wipes out of a large jersey cotton sheet. I cut the sheet into rectangles, folded them in half, and sewed up the edges to make them extra sturdy and to keep the edges from fraying.
Here's to your baby's softest bum ever!
