I just did a huge cull. About 1/3 of all their toys are gone including reducing collections (200ish bits of plates, cups and play food to about 50, 19384829 wooden blocks to a small tub of the good stuff, halved the matchbox car collection). Anything that they haven't played with in 6 months is gone. Anything that gets a cursory play and then dumped on the floor is gone. I have pretty much stripped it back to what I consider to be the basics: blocks, trains, cars, toy animals, dolls and clothes, play kitchen, a few favourite stuffed toys and the good quality puzzles. You know what? They didn't notice! Apart from being delighted that I set up the play kitchen in a way that's more user friendly and has had them playing 'cafe' for two weeks solid. They have not asked for one missing thing. And they're actually focused and more organised in their play because they're not wading through stuff and dealing with the distraction of me telling them to pick up.

I planned ahead, listed what I was culling and put ads on freecycle, for things to be picked up on a day that they were away. Anything that didn't go, I took to Vinnies.

I am SO GLAD I did this. No regrets at all, even if some gifts or things I had memories around went in the process. I don't miss any of it and feel so much better about the space we have and the effect it's had on both myself and the kids. Get rid of it Hun. Kids have grown and thrived just fine on the strength of a single rag doll and trees to climb. Your kids will do just fine without the majority of their toys.
