Yea, we do the whole toy donation thing at least twice a year, and have always done it so it's not weird to our daughter. Bonus is she understands that other kids will get to play with the toys, so she has fun picking out the ones she thinks these unnamed kids will have the most fun with. She now thinks that everything is supposed to be donated when you're done with it, which is kind of a cute and semi-healthy outlook (she told me that after we're done living in our house we should donate it to some other family).

It helps that they genuinely outgrow many of their toys during the early years. I was a military wife. I used routine military moves as a good excuse to cut back on the toys and other aspects of North American Affluenza. "We have a weight limit. We can only move so much. The new place will be smaller. etc"

Isn’t it a bit weird to donate to some other kid a toy that you consider not so good for your own child?

If you give it to Goodwill, they will sell it. You aren't forcing it on another child. Different people have different values.

If that idea offends you, I will say again: I also really like the idea of taking them apart, knowing they are unlikely to get put back together in working order. So if the idea of donating them doesn't work for you, go with that.

Or come up with some other solution. My comment in a forum in no way impels you to do as I said.
