Angela, your blog pages are set up, but are hidden from public view until you have added at least 4. Blogging is excellent for SEO. It signals to Google that your site is current and active. The best blogging schedule is weekly or more often, bu since that's probably too idealistic with your schedule, I've turned off the dates for the blogs. Dates ill still show up in the post url, but not under the post title on the page.
The ideal length for blogs is a minimim of 600-1000 words.
