I use a Washable wipe which is wet...then a dry one to dry her with...if I don't make sure she is dry then she gets sore...Kieren was exactly the same! X
Air for us! My washable wipes are stored damp - so by the time ive used one, and then got the nappy ready - DD's bottom is dry. If the wipe is more wet -then a quick brush with a terry towel & its all sorted.
