I have been researching into the various cloth nappy choices and want to be prepared when the baby arrrives. I was thinking of getting about 18 nappies - a couple of different makes but have been advised not to wash them all in case I want to send them back. This makes sense to me but at the same time I want to have nappies ready for when the baby is born. How can I strike a balance of having my nappies washed and ready and risking not returning them if they don't suit?
