Read this in Danbooru. Again, I still can't get used to Kaguya turning into a baby but the overall story really made ma smile and depressed.... and smile again.

If it was a normal human, the baby would be dead already just from the force of Youkai flying around.

Ugh my heart is still trying to solidify but no matter that was so cute

Why this has no Heartbreaking tag

What the fuck.
Though, now that I think about it, Okuu could've raised her without incident since she wouldn't have died no matter what.

Yep, this one still has me conflicted. Beautiful art and adorable premise but it just feels so unbelievably cruel of everyone to make Okuu go through all of that despair, terror and pain. The ending with Kaguya is supposed to be sweet but then you realize that, had they waited just a bit longer, she would have grown up and Okuu would have been spared all the mental anguish she had to suffer through.
I really don't like it.

I really wish Okuu was able to raise the child. She’s such a sweet mom in this. Does make me also want to see a comedy where Okuu and Orin raise a child
