Step one was to take every single toy in the whole house & remove it all to one room. That is known as the toy room. Every week she is allowed 10 toys from the toy room & no more. At the end of the week she can swap out any of the toys she would like to swap & keep any she would like to keep as long as the number she has is 10 (or less, but she doesn't ever pick less).
We've been doing this for around 2-3 months now & it's been going great. We've also done a toy purge of stuff she was ok with donating to the thrift store & I think it's getting to be time to do another purge. I'd like it if all her toys could fit in to 2 lg rubbermade tubs, right now it's about 4. When we were packing to move it was 8 tubs & that's just way too much.
I love this toy library system & it has really helped keep the house, or should I say every floor in my home, clean. I am also finding she is really focusing in & playing more with each toy instead of becoming distracted every 4 seconds by another toy.
