For my Daughter's 21st birthday I presented her with an album "Your first 21 years", having sorted through copious boxes of family photos since her birth. While doing that I organised all the folders into years so when it came to my Son's 21st his album was much easier to make up. I also included such special certificates, Swimming, Guides, Scouts, D of E with badges, etc. They both love them.
Recently had a good sort out of (now deceased) parents' old photos and destroyed all that meant nothing and kept only a few good ones, dating and naming where possible for when I am no longer around .
