The changes involving laudnering soft items sounds exhausting and problematic. Needing to wash everything weekly isn't fucntional. It will lead to a lot of soft materials being thrown out and the introduction of hard plastic materials. 

As it is, our school is constantly doing laundry. We have two sets of washers and dryers. Most days we wash 4 full loads of laundry. Washing all our stuffed animals, cloth dolls, dress up clothes, pillows and removable covers weekly will easily add 4 loads of laundry a week. As it stands, we are washing all of these materials regularly. Everything that is mouthed, or otherwise soiled is getting washed. 

Beyond that, it takes us hours to fold, sort, and put away all the laundry. Adding in every cloth item in the school will not work. If it does make it through the laudnry, it's unlikely it will make it back into the classroom in a timley manner. Untimately, many materials will be removed from the classroom. 

Children need soft places to relax, to feel safe, to safely throw, to safely jump, and so much more. They are necessary. Children will miss couches, and stuffed animals to cuddle. It will not add value.

It would make sense for couch cushions to be laundered when soiled, and monthly. Weekly is simply not fucntional
