So yes, yes I do

And I'm a big advocator of it. I started a few years ago when I realised that I hardly had any pictures of me growing up.
I want my kids to grow up with lots and lots of memories to look back on. What about if I or my wife start losing our memory as we get older?
Also for future generations to look back on, I want them to see our family life as it was in the early 2000's.
I haven't taken as many over the past few months, as there hasn't been much eventful happening, but I try and take photos of everything eventful, however small. Even if it's just a picture of some christmas decorations, or my little boys first attempt at a sandwich, it all gets snapped.
Even now, I'm looking back on photos thinking 'Wow, I'd forgotten about that!'.
I used to use the DV-Cam too, but since it got fussy last year, Ive only pulled it out on special occasions. (I have about 60 DVD's worth of raw AVI footage (15 gig per hour), backed up onto about 12 dvd's of compressed MPEG footage).
I don't document my extended family so much, as we don't see them that much. When our paths cross for an occasion I always do though.
