Great idea! There's a real market for your type of blog.
On first glance I don't see too many pictures of families or children (having lots of fun in Atlanta).
A feature idea, such as Photo Friday might get you more comments.
Get readers to send in their photos of family time spend at local attractions.
Almost seems like there are way too many ads.
Do you have a local community events listing?
I work for a community newspaper and can provide and endless amount of ideas on local event driven content.
Otherwise, you've got a good thing going!
Hope this helps!
