Some bloggers add their blogs to a blog "ring" where readers can just select to move to the next blog member by clicking on the button. These rings are usually set up by members with a similar subject matter - like rings for scrap quilters, stay at home moms, gardening, etc. Being a member can increase your readership. Watch for these rings on blogs you read.
I am not a ring member, but here is an example of a blog that is. This blog is a member of a ring called "quilt designers blog ring" - see the button on her sidebar to see what I mean:

I liked your blog and was able to leave a comment with no trouble. Best wishes to your newest family member and her cute big sister, too!
