Even though it has been a few days, put your baby in the bath, with a mild soap like a baby shampoo or so. Something that can break up oils. Let her slither in it for a bit and then "rinse" her off with clean water and dry her with paper towels, rubbing her down with them.
Also remove all bedding from that cage. Wash all deco, walls, water dish, hides. Put fresh / clean bedding in there, then the snake. There really is nothing else to be done at this point. Hopefully it is something that gets metabolized out of her system. Its very encouraging that she hasn't had worse symptoms yet..
Hope she will be just fine !
