Redirect with added subpage

I added the blog category to my permalink and having a hard time redirecting the old links.

For example:

http://dev32.thetoddlerfoodies.com/2016/01/07/sufis-atlanta-brookwood/
needs to redirect to
http://dev32.thetoddlerfoodies.com/atlanta/2016/01/07/sufis-atlanta-brookwood/

Where atlanta is the category.

I tried /(\d*)/(\d*)/(\d*)/(.*) => /atlanta/$1/$2/$3/

But that doesn’t seem to work. Could you please help?
Thanks!
