Mammals respond to smaller versions of themselves only with disproportionately large heads as juveniles. Dogs are apparently able to distinguish adult humans from children in the same way.
I have read about the above - but not about large eyes. That doesn't rule out that it may be possible.
We make teddy bears, koala bears, penguins and human dolls with exaggerated head sizes so human buyers will think they are cute, for example.
You know, if you're looking for an ethology thesis topic, the big eyes thing could be very interesting... unless of course it's already a done deal.
