I've seen people who are anti-baby describe babies, or children in general, as human larvae. This is generally done in order to make them seem weird. While I feel like this statement is wrong, I can't quite put my finger on exactly why.
Many definitions of "larva" specify that they must metamorphosize, or go through significant morphological changes on the path to adulthood. However, tadpoles gradually change form, rather than metamorphosizing, and hemimetabolic insects have larval instars that aren't substantially different from adults, aside from being sexually immature and smaller. "Sexually immature and smaller", of course, also describes babies fairly well.
Unfortunately, I'm no biologist and my knowledge of what defines animal young as larval vs. non-larval is rudimentary, at best, so I'm not sure if there's a more precise definition of "larva" than the one I found on wikipedia, which would disqualify human babies. What traits differentiate larva from non-larva, and which of those traits to babies lack?
