Before your child is born, start a treasure box to collect wonderful momentos for their life. On the day that your child is born, add a copy of the day's newspaper(s), a list of top 40 songs, a few notes from yourself about the day and what's happening in the world. Add to it as your child grows. Put in things like birthday and Christmas cards, first clothes & shoes, etc. This will all become a time capsule that your child can treasure and add to all of their lives and show to their children.
