I had always thought that a complete metamorphis involved a pupae stage. The argrument that a froglet, being just a smaller version of an adult frog, might lead one to believe that humans (post natal) undergo a similar bypass of the pupae stage, in that as human babies, they do resemble humans, but are grossly dissimilar in proportion, human's baby's heads being about 1/3 of their total body length. Being a parent of a very active seven year old, I truly do miss the lack of a human pupae state. At any rate, I'm quite rusty with my science, and am most probably in error, but would greatly thank anyone who can tell in just manner I am mistaken.
Thanks, and all the best, and with the best of intentions, Rick
