My son's birthday is fast approaching and it's a big one; he'll be 10 years old and is excited to be "double digits".

Planning his birthday celebration made me a bit melancholy.  I decided to look through old photos to remember when he was small enough to curl up in my lap. What I also found were the interviews I've conducted with him every year on his birthday since he was two.
This interview idea wasn't mine. I'm sure I read about it in a book or magazine but these notes of who he was and what he was thinking are by far my most treasured possession.

If you'd like to try something similar with your little ones I'd suggest keeping the questions simple, writing down the answers verbatim and asking some of the same questions every year. Putting their hand print or having them sign their name to the interview sheet is also a great touch!
