pretty much the only toys i get for my kids to get are lego compatible bricks. with those it doesn't make a difference if you have 1 or 10 kg of them. just add to the pile.

no books in my house because we are moving to often. but i grew up in a library. my dad probably has 10-15m worth of bookshelves. from my granddad we inherited 3 or 4 times as much. but they were both collectors, curating their collections with care. still, sorting through those books to figure out whats valuable is a lifetime occupation. and i can see how a lot of books can be overwhelming if you are not into that.

a year ago i heard about someone passing away leaving behind a house with a collection of 75000 books. the cost to sort through them would be higher than the value of the collection, so instead it all goes to a landfill because i a not even sure it can be recycled or the cost of getting it recycled was to much too.

There are a few types of toys that my wife and I are still ok with getting and Lego is one of them. She's started using the phrase "more really is more" to describe the category. Basically, it's systems where you build something and the more you have, the more things you can do: Lego, Brio, Magna-Tiles, Hot Wheels track, etc. Even things like Pokemon cards (if your kid actually plays the game) can fall into this. You do have to be careful not to end up with too many of these systems, especially really similar ones.

We're also still ok with getting books. We have a few too many for our shelf space, but at their current ages, our kids are aging out of books about as quickly as they receive new ones. I just need to do a better job of giving away the old ones more regularly.

Yes! I've run out of ways to tell MY parents not to get toys for my kids for Christmas/birthdays. I can ask directly for no physical things; I can suggest tickets to shows or evens, memberships to museums or zoos, etc; I can point out every time they come over that there's not enough space for the things we already have; I can tell them what sorts of clothes the kids could use instead. They're still going to get each kid a "showstopper" (toy workbench, Big Wheel, something physically large) plus several cheap plastic trinkets... plus the clothes.

And that's just my parents. I can politely talk to them about not getting physical things for my kids, but then there's all of the extended family that loves to get them big, cheap plastic stuff, too. I know they're trying to be generous and don't really understand the fallout, but I'm starting to reconsider the whole "it's the thought that counts" idea.

I need to do a better job of helping the kids periodically go through and give stuff away, but 1) try explaining to a 3-year-old why giving away your toys is a good thing, and 2) the influx of new things always seems to outstrip the rate at which I can find time to get rid of stuff.
