We have a keepsake box for all of our little ones. We keep teeth, our latest has the umbilical cord and clip, haircuts (for boys only), pictures, special outfits/shoes, special items from pregnancy to age six, outlines of the baby/child on large roll paper, books, toys, cards, some have cassettes of first words, newspapers from the day they were born, etc. etc. basically anything special that they would like to see and show their wife, kids, and grandkids later.
