Infants and young toddlers have their own individual toy center (book shelf, toy box, rug, table, selection of toys/books) that is cleaned up at the end of the day for disinfection. This has always been my policy, pre-covid. Littles don't share.
Preschoolers have to clean up one class center before rotating to another. Normally. They are taught to wipe down toys and wash hands, themselves.
**For COVID, though, they are only rotating centers once per day, upon arrival. I disinfect each center at closing and they each move to another the next morning.
Technically, they don't need to move since I set each center up with a variety instead of one theme/type (science, math, writing, blocks, etc.), but they are used to moving and look forward to it. I felt something needed to feel familiar to them.
