Magically Deaged Fics
Every fic i can find that is deaging and not age regression. There are too many fics for me too read them all so if it's unclear to me from tags and description whether a character actually becomes younger i will add the under review tag and go through it later.

Summary
“Aizawa, are you sure I’m the best person for this job? There are a lot more qualified people on campus. People who have been teachers for years, and—”
As All Might spoke, Midoriya Izuku crawled the length of the couch, ducked under All Might’s arm, and made himself comfortable on his lap. All Might’s hands rose into the air, as though unsure of what to with his arms now that he had a toddler curled against his stomach like a cat seeking the warmth of its owner.
“Um,” All Might said.

Summary
Tim gets de-aged, and tells absolutely no one.
He also, in no particular order, gets therapy, does a lot of crime, channels his inner cyberbully, steals another Batmobile, moves to Metropolis (temporarily), causes an Arkham breakout, gets kidnapped, kidnaps someone else, and accidentally becomes a supervillain somewhere along the way.
Parental supervision is for losers.

Summary
Normally, when something really weird happens to the Batfamily, traveling through time or turning into animals or swapping bodies, they figure it out and pretty quickly move back into normal life. (Well, normal-for-them life at least.) But normally, when something really weird happens to them, it happens to them as their vigilante selves at night. It doesn't happen to the Wayne family in broad daylight and in public.
When Dick, Cass, Jason, Tim, Duke, and Damian are physically de-aged and all of Gotham knows it, they must comply with the regulations that have been put into place for "civilians" during this sort of thing. That includes going to doctor's well-child check-ups, and to social worker visits, and, worst of all, to school. The whole thing will be a weird and confusing mess, and everybody is sure to hate it.
(Everybody is sure to hate it, that is, except maybe Bruce, who is more confused than everyone but is experiencing having all his children around as actual children for the first time.)

"Did a two year old just outrun you?" Jason asked, wanting to make sure he wasn't hallucinating.
Bruce clenched his jaw. "I didn't want to hurt him." He growled.
"Liar!" Tim piped up from under the desk.
Jason was starting to like this version of his successor.

Summary
For the chain, Time was the one to look up to— whether that be in seniority, in experience, or in height. He was a solid foundation to rely on, so what happens when that man must come to rely on them? While some of the heroes may be experience with children, taking care of one that's destined to save the world is a different story.

Summary
The man that was once Jedi Master Obi-Wan Kenobi, GAR General, knew that his death was finally here. Just as he was struck down he made a wish. As he disappeared from the mortal plane, he didn’t realize the Force had been listening. When he opened his eyes, with a younger body and in a time long past, it was apparent that the Force took a somewhat creative interpretation of his last thoughts. However, the man that was once Crazy Old Ben, Wizard of the Wastes, wasn’t going to squander this second chance. After all, he had a padawan to teach and the galaxy to save.

Summary
After sacrificing everything to save his world, Peter is flung across dimensions and finds himself alone in Gotham, a city as unforgiving as the new powers he’s struggling to control. As Peter’s spider instincts sharpen, he navigates Gotham’s dark underbelly, evading criminals and catching the attention of the Batfamily.
But to Gotham’s vigilantes, he’s just another dangerous meta—until they realize he might need saving too.
