I have a large room to use for my day care. It is developmentally appropriate and child centered. I was encouraged to use cubbies and bins for organized storage. My cubbie unit has 20 bins. Toddlers like to just pull the bins and dump the contents onto the floor . This is a constant battle for me since they can dump the bins in a matter of seconds leaving a huge mess to sort and clean. I have them help me sort them and put them back only to have them repeat the process. I am trying to think of a solution that still keeps the space child centered but limits the aimless dumping of toys.
