The 3 methods I have heard suggested:
- Water only - just wet cloth wipes in the warmer or plastic container. I don't like this one as much because it seems like there should be some kind of cleaning solution involved. I have seen baby poop!!
- Water plus a few drops of mild soap such as Dr. Bronner's (I love the peppermint, although they also have an unscented baby versions)
- A concoction of water, baby oil, and baby wash...this one is too complex for me. I am under no delusions that I will have the time or inclination to keep up this kind of mixing long-term.
