I use bottled water as we keep cases of it at our house.
So, I pour off (OK, drink) a little water out of a standard size bottle to make some room. I add one drop each of lavander essential oil and chamomile essential oil, a very small amount of baby wash (maybe 1/4 tsp), and a generous amount of Burt's Bees Baby Apricot Oil. I shake it up and pour it over the wipes.
It smells fantastic and works great!
