I use cut up muslin squares and they work a treat!! Every morning I fill the old pampers wipes container with warm water and I pop the used muslin in my nappy pail to be washed with the nappies. They're great!
Would never dream of spending that much money on wipes!
Bought some terry wipes from the nappylady v cheaply and just use with water in one of those silly top and tail baby bath bowls - stick in a nappy bucket before washing - much cheaper - sounds like a real faff and v expensive to me. Not sure about using essential oils on bottoms - why not just use water?
