wooooo!!!! It is a wonderful idea, I would never have thought of rotating toys because children suffer and cry if they have to get rid of their toys, especially some that are already very damaged by their use and there are others that, as you point out, are the love of a summer, so to speak, but that is an excellent idea. I solved the problem of the large amount of toys especially on birthdays and Christmas with an idea that I read a long time ago and I liked it a lot because besides helping you not to have large amounts of toys it teaches them the value of sharing, so every time you give the children a good amount of toys I invite them to keep only one or two and all the rest we donate to a center for children with limited resources that day I try to take the toys and make a meal with the help of other people who also support and spend an afternoon in the company of the children of the center sharing. I really like your system, please patent it.
