Need your help ladies

My best friend is doing a time capsule for her son who just turned one. I am his godmother and 'aunt.' He is going to open the capsule when he is 21. I have some ideas but wanted to know if you lovely ladies had any more.

Besides for telling him how much I love him I was going to tell him the story of how I met his mom, how excited I was when he was born, etc.

I was also thinking of writing up a trivia thing like what events occurred in the first year of his life such as world events, # 1 movies, songs etc. I don't know where to find info like that. Do you girls know of any sites that would have this info or do you have any other suggestions for me?

Thanks so much!
