Remembering the Little Things

So I totally stole this idea from another girl's blog. But I thought it was such a good idea because I forget all the little things that you want to remember about your kids. The cute noises they make, their first words, first laugh all that stuff :( And it seems life goes by so fast you think "oh I'll remember or I'll write it down.". Sure I will.
On this girl's blog she had her son's pictures taken for his 2nd birthday and she wanted to document characteristics and phrases from his 2nd year. I thought this was perfect and cute, especially since these are the kinds of things I want to scrapbook for Gwen (one day), you know when I have an abundance of free time.

I just put this together in about 30 minutes between wrangling a two year old and a puppy so I'm sure many of you could put together a cuter and more finished looking one. But I really like how it turned out. Plus with it being digital you can totally edit it or change it or do multiples.
What kind of things do you do to help remember and document your precious memories?
