How do you show nav links from pages to posts?

Hello,

I’m getting a bit lost. I’m setting up a site which I want to look like a static site. Have created some test pages which can be seen here – http://www.kidspartybags.biz/blog/”

I would also like to include one area for posts as in this page http://www.kidspartybags.biz/blog/?p=1″

My problem is how to get a nav link included from my main pages to the blog post section, plus my left hand side bar is missing from the post page, so not sure how to fix that.

Any advice would be appreciated.

Many thanks

Myles
