LOL sorry if I confused you!! Yes we re-wear our clothes but I just put the "worn" clothes in the drawers with the "clean" clothes. I don't think they'll contaminate my unworn clothes if they are clean enough to be worn again anyway!! So if they have dirt or smell then they go in the laundry, otherwise they go back in the drawer. Unless you are talking about re-wearing smelly/dirty clothes (maybe to work on the car or dig a garden??), then I'd say definitely do a separate drawer or bin!!
Co-sleeping is really wonderful when your child actually SLEEPS!!
