Interesting story in the NYTimes about “cuteness” and its biological underpinnings. We found out last weekend that Callum was born on the same day as the panda cub (Tai Shan) mentioned in this piece. Callum was ahead in growth rate for a while, but the panda has now overtaken him. At last measurement, Callum was a little over 17 lbs, while Tai Shan has hit 25.
