I know what you mean about over estimating 2.5's.
I've got one on my wall that I was sure was 3.5 or older when we were viewing him on pictures. But after shooting him, I'm thinking he might have been 2.5, just didn't have the body weight I was expecting. He did have heavy tarsal staining though, so maybe he was 3.5.
