I did some journaling for both but it was the photos with the second that make it a wonderful memory (we took monthly photos of the first and posted them to our website for friends and family). The photos from the 2nd pregnancy, though, were done professionally. Some of the photos include my hubby, some my daughter and others with the three of us holding my belly. My girlfriend did the photos and did the most wonderful job. Anyone in the VA area check her out: http://jesswilliamsonphotography.com/index.html
I've the most beautiful book of photos and every time I look at it I feel so fulfilled in that pregnancy (and it was pretty crappy but you can't tell by the photos!!).
