How old is this blog!?

I have been writing elsewhere lately, but looking for a photo I saw the blog post when Holly became a teenager. http://sandradodd.blogspot.com/2006/07/three-teens-i-have-three-teens.html

She's been 21 years old for over a month now. She, Kirby and Marty will be all in one place right after Christmas and I'll try to get a photo of them together.

Their teen years zipped by, it seems. It's been over a year since we had the last of our 19-year-old children. I love them.
