I liked this idea the most:
...invite your child to pick a few toys that he has outgrown. Together, pick a charity or friend who will be your beneficiary. If saying good-bye is hard, take a picture so that your child can preserve the memory in an album of outgrown toys. Let giving away toys be a ritual by which you celebrate your child's growth.
My oldest is a memory keeper. My youngest is just in denial about thinking he still plays with certain toys. I have already started an album of artwork/schoolwork through Shutterfly. I take the photo, add it to the album and toss the paperwork/artwork. GASP!! Well, I do save a few favorites, but MOST has to go! I just don't have the space to store a box for each kid, each year of elementary school. That would be about 24 cubic feet.
... I LOVE the idea of adding photos of beloved toys/stuffed animals/memorabilia. Easy, relatively cheap, and it will sure weigh a lot less and be easier to pack up for the next move! I mean think about it: you return to your parents home for a visit and mom hands you about 16 large boxes of all the stuff she's saved for you. Wouldn't you rather have a book with photos and stories of the beloved items. I am so all over this!
