Most kidnapped kids were ARed offscreen, with only one boy seen being ARed, ending up in oversized clothes. There is an aftermath with another boy, and the other babies are shown in oversized clothes, though it's hard to tell.
Ubume is actually the spirit of a young woman who lost her baby to cold and hunger. When the monster is defeated, it reverts into the woman's spirit and is reunited with her child's spirit, and they fade away peacefully; presumably into the afterlife.

Another jealous girl turns his daughter into a child.
The story ends well, with the boy and girl hooking together for good, and the dad deciding to stay a teen, with another girl falling for him. In chronological order:
- Dad into young adult, Boyfriend into kid, Dad into teen, Girl into child.
We see more of her in baggy clothes. Also brief AP as boy returns to normal age.
Tragically the girl runs off to hide and the scene cuts before we see her grow back to full adult size.

Honto ni Atta! Reibai-Sensei

Young female teacher Kibayashi-sensei's hobby is speaking with the dead and exorcism. She knows everything about the other world, but nothing about our own.

Since her mind is partially changed as well, she acts like a child by squirting the rest of the youth water all over her students, causing mass AR among the kids. There's no RN, but the next chapters show everyone at their normal ages again, so I assume they turned back off-panel. It's sadly poof, but really cute with baggy clothes.

His own preferred girl is a 50 y.o. chubby human woman, who he considers incredibly attractive because she's so much younger than him (Zel has been visiting her for 30 years since she was still young and hot). The halfling judges them entirely on their age, and gives the human the edge for being not as old. Conventionally speaking, the elf is obviously far more attractive, but Stunk is the only one to think so.

Alessi's phantom shadow turns Polnareff into a child. Along with his smaller stature, Polnareff's mind starts reverting as well, causing him to gradually lose his adult memories. Unable to ask Jotaro for help, Polnareff's Silver Chariot is also shrunk by Set's power. Barely managing to escape, he is picked up by a woman who takes her home to treat his injuries. However, Alessi sneaks inside and attacks.

Ep33, 59, "Set's Alessi, Part 2", 3/6/2015.
- Alessi attempts to drown Polnareff. He used his power to turn the woman into a fetus that will die soon. Polnareff attempts to escape with her, turning even younger everytime he touches Set's shadow. Using a mirror to hide himself, he manages to get the drop on Alessi. Alessi manages to hit Jotaro with Set's shadow, only to find that even as a kid, Jotaro is still powerful and ruthless, as he knocks Alessi out, undoing the age curse on both him and Polnareff. The woman is back to normal as well.
I didn't enjoy the part when the woman had regressed to a fetus, I would rather have her a baby than a fetus. At least they could've shown her regression. Not sure what was more baffling; Polnareff keeping his composure, the time to set up that trick, or how Alessi lost in the first place. I assume knocking him out deactivated his stand and the AR-effect it possessed?

A 30 y.o. woman was ARed earlier. She has already begun to grow back up, as seen by the initial tears in her clothing. It looks like she took off her too tight panties. The process rapidly completes before an astonished onlooker. The original AR of the woman was off-panel - the first time she showed up she was already a child.

A bit creepy, and the AR is infuriatingly short. Villains with time-control powers use them on two women: one is aged to dust, while the other is transformed into a newborn. While the OA is shown in some detail, the AR is, OF COURSE, glimpsed over. The poor OA'd female is shown withering into a crone, then a skeleton, and then dust; but the AR cuts away as we hear the other female scream. Only a tiny panel is shown of her newborn hand, and part of her clothes on the floor (yeah, you can tell I'm salty; I expected much more, but as with almost every single AR I found lately, the content is severely disappointing).

Kizumonogatari II: Nekketsu-hen
- (demon ARed form, RN AP AA spurt) 2016, "Monogatari" series 2nd movie.
Loli vampire Oshino Shinobu AKA "Kiss-Shot" is actually adult but takes a younger appearance due to circumstances. She turned from a buxom princess into a child offscreen, by biting the protagonist and transferring power to him.
The movie features 2 AP events. She transforms offscreen from her child form to her preteen form, and another scene features her transforming from preteen to mature teen form. She grows up rapidly while sleeping. It shows AP process for the upper body and her lower body from the side point of view. Since this happens in a loose dress without underwear, we can see her breasts expand and fill the looseness of the dress, while her legs expand out of the bottom of the dress. It's done in a gag-like fashion with funny sound effects, but the process was excellently detailed.

- (ARed, AP RN) The diabolically sexy anti-heroine leers out at us from the cover of volume one, skintight outfit stretched over acres of curves. Then you open the book and find out she spends most of her time looking absolutely nothing like that. A witch with the power to control magical guns, Kurohime once made the mistake of challenging the gods... and for her foolishness, she was changed into a little shoujo named Himeko. Now she can only regain her true form and her powers when she is in love. After 10 years of living with this curse, she meets a skilled gunfighter named Zero. It turns out that when Zero was a boy, adult Kurohime saved his life, and he's been in love with her ever since. Most of the art's in a simplified if skillful shonen-manga style, but when Kurohime manifests in her full adult form, she's rendered with the detail and salaciousness of a more seinen/mature title. Too bad she can't stay that way, since after only a few minutes of being in that body, the adult Kurohime's heartlessness kicks back in, and poof! she's a Size 2 all over again.
