He heheheheh yep. We all do this to some degree or another. We were "given" a "time capsule" from the hospital with each of our babies. A metal tin about a foot tall, that I stuck the things I really wanted to keep inside. Their ultrasound photos, the bloody knit hat from the hospital (ewwww), hospital bracelets, first paci, newspaper from the day they were born, etc...
Then it tapers down until they learn to write and start school and it becomes an even bigger problem....they are ALWAYS bringing home loads of papers and artwork.... lol. Or writing notes to me or each other. Or writing stories and illustrating their idea of a comic book. They'll also have report cards, progress reports, Honor Roll certificates, standardized testing scores/results, project notebooks, science projects/boards, and on and on and on....
What helped me get through the first few years of school, was just putting EVERYTHING they brought home in one container until the end of the year.. then sort through it and pick out the things most representative of their work as it progressed and matured. Also, take photos of things....
I gave away TONS of clothing... but kept out just a few items that were special to me for each child. (My son's first shoes and the onesie my husband first put on him and brought him home from the hospital in, my daughter's first Easter Dress, etc).
