Here are my observations...all of your babies like going upside down, your right side must be the natural side for you to hold them, and the camera got further away over the years...and of course they are all cute babies!This might be weird, but I kind of think they look more alike upside down. Maybe that is just because they are close in age.
I just realized that the camera may not have been further away and it may just have been how they were cropped.
No you were right...camera got further away! I am always complaining to Joe that he takes my picture too cLose up and is finally listening:) And YES I hold my babies on my right side although the left side would make more sense (to free up my right hand).
Dad's observation is that Isaiah and Hannah look alike upside down
