I get it. Our parents saved all our old toys for our kids. I get a group text from my mom about once a week about toys, exercise equipment, gaming systems, and all sorts of furniture either from childless friends who are downsizing or that we don't even remember the grandparents having. I'm always grateful when something is damaged from being in the attic or otherwise easy to turn down. I have a relative who is storing the belongings of children who moved across the country a decade ago (they did ask her to hold onto it). Even if it still fit, they almost definitely don't need or want any of it. Even stuff with actual sentimental value* is weighing you down. Get that dumpster and toss it. It affects your mental health and ain't nobody got time for that.
*Car parts probably don't count.
