I too rotate out most toys. When I started I had a lot out, but quickly learned that that just isn't of any benefit to them...they would just take every single toy out of the buckets and throw! Talk about HUGE mess/missing pieces! So, now I have small buckets of stuff (organized by theme) I pull out 1 at a time throughout the day for example: Kitchen/food stuff, tools, blocks, bowling, floor puzzles, cars & tracks, trains & tunnels, sorting bins, blocks, musical instruments, puppets, farm, wooden puzzles, play dough stuff etc... I also only keep a limited selection of about 10 books that I rotate out daily.
