Managing toys for twins is not just a chaotic but also an expensive affair. One of the ways I deal with this is by practicing 'rotation'. I make sets of few toys which include soft toys, thinking toys (like puzzle, blocks, etc ) and moving toys (like balls, instruments, etc) and let my twins play with one set at a time. After a week or two, I give them a fresh set and pack the previous one. This way, even the old toys become attractive and new for them and their excitement level is always high.
