There are parenting blog rings, and you can just keep cycling through them, find ones you like.
My favorite way (when I get on a blog-reading kick, since I don't generally read regularly) is to just follow links from the ones I can find. I found a kick-ass blog recently just by searching for the topic I was interested in (attachment parenting feminism). And I found other cool blogs following links from there, and so on.
