YANBU!!!
I keep all that kind of stuff. DD's childhood stuff, from the late 1990s and 2000s (noughties,) and mine from the 1970s and 1980s. I also have 300 books, (half of them pre 21st century,) a dozen or so old toys, like a string puppet, teddy bears, dolls, several board games, and other various 1970s items,.
Also 500 vinyl albums, 700 vinyl singles, 350 or so compact discs, 25 or so cassette tapes of stuff I recorded off the radio in the 1970s, some posters of my fave actors and pop stars from the 1970s and 1980s, old calendars, old annuals, and 5 or 6 dresses I wore in the 1980s when I used to go nightclubbing (including the dress I wore the night I met DH over 30 years ago.)
I also have 1000s of old photos of my childhood and young adulthood, (and more recent ones!) and also loads of photos of my parents when they were young, and my grandparents, (born 1910s-1920s,) great-grandparents, (born 1880s-1890s,) great, great grandparents, (born 1850s-1860s,) and great, great, great parents (born 1830s-1840s.)
Some of the photos of my grandparents, and great-grandparents are from the 2 world wars, and are of them in lots of different countries.
I will never ever EVER get rid of any of it, and I hope I never have to move into a smaller home, (currently in a 3 bed house with a garage,) because getting rid of this stuff is not an option.
