"According to a study by the Australian Zoologist Konrad Lorenz, baby animals have larger eyes, smaller noses, higher foreheads, and retreating chins. He called this the “baby schema” and pointed out that this holds true for almost all species.
He has pointed out that this is an advantage in nature because the parents tend to favor babies that have the highest degree of these facial features."
"Some scientists believe that animal babies have bigger eyes, ears, and faces in order for the adults of the herd not to eat them.
They need to charm the older animals in the herd in order to survive. Especially among carnivores.
Since they have the same facial features as human babies (bigger eyes, higher forehead, etc) it could indicate that their babies are also capable of charming their parents. "
This isn't a great article on it, but I've read before about how babies are designed to trigger a nurture response in the shape of their eyes and the pitch of their wail. This kind of touches on it.
