Google Not Indexing New Posts

I’m not sure what’s going on, but Google is not indexing my most recent blog posts. The last post that was indexed was on Nov. 12. After that, nothing. The cache for my main site, vanessamphoto.com shows Nov.12 as the last time it was cached and that’s also when my last blog post was indexed. I haven’t done anything differently.

Any idea what I can do to get back in the crawler’s good graces? 🙂 The site is not new and I haven’t had any problems in the past. Suddenly, it just isn’t being indexed. Thanks for any help!
