Small, Medium, Large - Not Anymore

I have a cousin had a little boy named Jackson about 6 weeks before Addison. Then, I have another cousin who's wife had a baby 4.5 weeks after Addison. The first time we got together, we of course had to get pictures. After the first round, everyone referred to the photo as "Small, Medium, Large." (Addison is in the middle)A few weeks ago, we got the kids back together again and had to retake the pictures. We haven't taken another picture for about 6.5 months. We set them up the exact same way...however, it really can't be called "Small, Medium, Large" anymore.

Caylynn, who is the youngest, is the same (maybe more) size as the oldest, Jackson. Addison is the littlest now. The pictures are great to capture; however, there should have been someone filming the adults. I swear, we were saying the stupidest things and making the weirdest noises to get everyone to look at the camera. I think (between three cameras), we took about 40 pictures to get the best one.
