>>57854016>the vast majority of Pokémon can breed straight after hatching from an egg, but for some reason baby Pokémon can't do that?This falls under "Game Freak handles babies in a dumb way". Game Freak has no idea what the hell they are doing most of the time and are too stupid to think even a day ahead, their creative process amounts to throwing shit at a wall, not caring if it sticks, dicking around, and naval gazing until a higher-up tard wrangles them into making something halfway coherent. Baby Pokemon only exist because one guy randomly decided Gen 2 needed a bunch of moeblobs to appeal to women and little girls because the pure testosterone oozing from Meganium, Jumpluff, and Corsola might scare them away. Now clearly, there's nothing wrong with this, but when your only thought is "make cute thing" without giving a shit how it actually fits into anything, you get stupidity like Jigglypuff getting a baby while Kangaskan doesn't. It's like how Megas only focus was "make broken shillmons even more broken, pandering to KANTOOOOO and dick sucking CHARIZARD".
Pic related illustrates one of your issues with "baby" Pokemon. So many first stages invoke baby/child imagery, and some are flat out based on larva yet those are sexually mature somehow.
>AND THE PARENT NEEDS A SPECIAL ITEM TO PRODUCE THEIR ACTUAL PRE-EVO???Game Freak retconned this in SV now if a Pokemon has a baby, that will always come out of the egg, though I'm sure it had nothing to do with making sense and are just too lazy to put incenses in every game. Though my headcanon was the the incense slow the development of pokemon in the egg so they come out as preemies though I suppose babies being the result of trainers intentionally putting the health of pokemon at risk for the sake of cuteness isn't the best endorsement for babies.
