Gargh, in my sleep deprived haze this morning, I left my big post on the screen and forgot to hit "post". Ah well, will post it now, then catch up on the thread. :)
Hiccup I also was inspired by the toy rotation blog, so I pulled out all the baby / shared toys, and made a huge chuffing mess! I sorted them by category (thinking / moving / pretending) and weeded out anything broken, or missing parts, or too young for ours DDs. I then split the 3 piles into groups, one category at a time. I already had the ikea drona boxes that the toys were "in" (read, all over the floor with discarded empty box near by) so I lobbed the sets into those. One of the blog pages showed someone using big ziplock type bags for the sets, and mentions someone else using shopping totes. I reckon anything you have that's big enough to store a set together is fine.
Very glad we started with the rotation. I had 3 whole days of the Christmas holidays with both DDs playing nicely together, no snatching, no squabbling over who had which toy first. Much easier to tidy everything up, and both DDs managed to help. Then Christmas hit, and it all went wrong, but for 3 days it was glorious! 
I have finished Kondoing the kitchen, and it's lovely. I know it is suggested to clean as you go when cooking. It's a great idea, but the practicality of it never quite worked. I always had to pull things out to get to others, so to put them back, I had to pull everything out again. Counter space was at a premium, so I didn't have much room to work with. So as I cooked, everything just gets pushed to the side, ready to be put away later. It works now! Use something, put it away! No clutter on the counter means I can wipe it down in seconds. I'm thrilled! Plus, for the 4th morning in a row, I've come downstairs to a .... clean, tidy kitchen! 
Sorry for the boast, but I'm so pleased, and surprised, very surprised.
