A nay.
Baby Pokemon, while they make sense, just feel like dex fillers and a waste of time imo. I'm not even sold on their cuteness since my tastes are towards cool looking Pokemon. However, this only is how I feel about baby Pokemon introduced after their family, Pokemon like Chimecho and Mantine should have got evolutions instead of making them less viable. I'm cool with first stage Pokemon that are introduced in the same gen as their family.
This pretty much sums up my opinion. Outside of the games and from a lore perspective, fine. Baby Pokemon do make sense. But what doesn't make sense is how you have to have Pokemon holding incenses to get their younger forms beyond Generation II, as if their younger forms are unnatural and they are supposed to be in their older forms. So that breaks the whole immersion and the lore perspective. I understand they want to maintain game mechanic continuity, but I'd rather they just do flatout retcons. They're already doing it in ORAS.
Also, the things I find cute tend to be a bit different than most people. I usually like older, more teenage-looking creatures (like middle stages) rather than first stage. That small stereotypical body with huge eyes and a big head doesn't cut it for me. I usually want to punch most baby Pokemon in the face because their head just looks like a punching bag to me. It isn't cute, it's just unappealing.
The only one I can think of off the top of my head that I like is Riolu, but that one was introduced in the same generation as its evolution, so it's kind of a necessary thing unlike those that are added later.
