I have purged many of my toys over the years to be honest and opted for 'staples' in the playroom that are always out with a few things for rotation based on skill (aka puzzles of varying difficulty, some seasonally appropriate materials (aka Xmas, Halloween) and than invitations for the older crew - smaller manipulative things that only come out in the playroom when everyone is old enough OR during quiet times when the babies are sleeping - they are stored in a cupboard in the playroom) ... anything else I want for 'rotation' I will BORROW from the local toy lending library so that I am not having to STORE it!
