I hear you about the amount of stuff coming home from school. With 2 in all day and 1 going 1/2 day to pre-school, I KNOW we could fill a drawer a year in a standard file cabnet if we kept everything.
I know exactly what you are talking about. Plus to top it off I am that rare person that keeps every form of correspondence, artwork, homework, etc from my kids and boxes it up at the end of the year. Someday I will need a bunker to store all of the stuff.
