@yourisekaiwitchess Babies make everything better, don't they
? I also collect a few baby manga to read later, so I always have a stock to go through if I am in the mood (and I have the tendency to leave good stuff for later).
I just thought of a few, but somehow, the weird ones ended up being more than the normal baby manga.
It's an elementary schooler, but
Forever Honey's kid is very cute.
Koneko Hiroimashita + its sequel. It's very simplistic since it was originally a pixiv manga, but it's sweet nevertheless.
Shounen no Ato I feel like I'm mentioning this a lot lately... this is probably the closest thing on the list to No, Youna. (which I also like a lot, incidentally).
Now this feels kinda out of place since its a battle shounen, but hey, it's a manga with a very prominent baby and it's VERY entertaining.
Beelzebub, anyone?
I've been rewatching the anime recently, but I remember reading
Daa! Daa! Daa!'s manga too, a long time ago. Sure, the anime is better, but the manga was good too. Rough start though.
And this is another one I keep throwing everywhere recently:
Familyman. It's the family's story more than anything else, but the kids are really young and have their moments, so...
Mentioning this next one here is actually a spoiler. The child character plays an important role in the story, but they only appear halfway through (iirc). There's lots of fluff though. Title's under double spoiler buttons.
Papa to Arukou is very cute but very short. Robot kid
Hoshi no Ko's MC stays as a kid for a few chapters, and it's already a short manga, so I think it deserves a mention. Extremely heartwarming.
Now I haven't completed this one, but
Sodatechi Maou has a cute kid and a doting proxy dad. It's been awesome for me, and I hope it stays that way.
