I have two big storage units that we had made specifically for the big blue ikea tubs. It's amazing how much can fit in there! The tubs have specific toys in them, for instance 3 are used for the train stuff, 1 has dress ups etc. i was never very good at rotating stuff so needed something to contain everything! I am good at donating things the boys have moved on from, I do keep some things for the grandchildren too!
