Yes, a baby is threatened and in severe peril for a. Extended period, crying. Several older children are also threatened, though all survive and none appear to sustain any injuries.
When they are fighting a monster, Hawkgirl hits the monster in the eye. Green Lantern creates a machine that constantly stabs the monster in the other eye. Later in the movie nanobots are seen crawling into Superman’s eyes and completely covering them.
No gore, very little blood. A characters spits out some blood in the opening scene and has some cuts on his face. This is in the snow so it is extra visible, but the movie is very safe even during fight scenes!
35:40 DIALOGUE/IMPLIED. Hawkgirl attacks a kaiju's eye then asks for help stating "My knee! Guy, help!" seemingly restrained in the kaiju's eye by her knee. Nothing is explicitly shown.
1:41:07 VISUAL/SOUND. After the line "My brain will always win! Brain beats brawn!" is said by Luthor: Ultraman pins Superman against a sewer vent. Superman grabs his wrist and damages it. Safe after 1:41:15
1:47:05 UNCLEAR SOUND/IMPLIED. Shortly after Krypto begins destroying Luthor's toys and right after the line "Hotel down!": Superman kicks Ultraman's face into a platform then grabs Ultraman's leg and throws him with a crunchy sound. The leg is not shown and it seems the platform and Ultraman's face makes the noise, but it may be triggering. Superman then swings Ultraman by his leg into rubble, but there is no accompanying sounds indicating limb trauma or visual damage to the limbs. Safe once the theme swells and Superman is shown in golden light (1:47:23)
1:48:14 VISUAL/SOUND. Once Superman finishes his laser spin move, Ultraman tackles him, grabs his arm, damages his wrist, then flips him and damages his shoulder. Superman is restrained by Ultraman, and breaks the restrain by further harming his shoulder (visual and sound). Superman then throws Ultraman off of him, sighs heavily, and fixes his shoulder (visual and sound). Safe once Mr. Terrific is on screen and says "This ain't playtime!" (1:48:58)
1:50:50 VISUAL/SOUND. After the line "...you patronizing clown" Krypto attacks Luthor. The first bite is accompanied by a crunchy sound. Krypto then continues to "ragdoll" Luthor, though nothing is clearly shown. Safe after Superman says "Dude." (1:51:15)
1:51:44 IMPLIED/VISUAL. Just after the Daily Planet crew is seen celebrating, Luthor holds his arm in a way that implies it is dislocated or broken, but there is no clear visual damage. Safe after 1:52:50 (or once the crowd cheers).
1:54:07 IMPLIED/VISUAL. Shortly after the soft guitar music starts and Fleurette says "Mom!!" Luthor his shown with his arm in a sling. Safe after 1:54:28 (or once you can hear Krypto snorting).
Mentions of torture. *mild spoilers* Superman is exposed to kryptonite, which looks very painful and distressing. Rather than physical torture, he’s tortured psychologically by having someone who helped him brought in and playing Russian roulette. The whole thing is pretty distressing, even if it’s not traditional torture.
A baby is kidnapped and held hostage to ensure his father's cooperation. Lex trapping dozens of people in his private pocket universe prison could also certainly count.
MODERATE:
In the opening scene in Antarctica, after the expository text says that Superman has lost his first battle, we see Superman crash land in the snow. (This is shown in the trailer.)
MODERATE:
Superman suddenly enters Lex Luthor's office, crashing loudly through the door. Here's the scene on YouTube: https://www.youtube.com/watch?v=0LV7y_HnQr4&pp=ygUhU3VwZXJtYW4gM
MINOR:
At one point Superman is pushed through a portal, and after he sees another person sitting down, a glass door loudly closes behind him.
MAJOR:
Jimmy walks down an alleyway at night; he is suddenly grabbed.
MINOR:
A woman talks on the phone in a dark room; eventually some men come barging in.
MINOR:
A world leader is asked to evacuate the building, but he refuses. We then hear a window smash.
MAJOR:
Near the end of the film, a jump scare happens shortly after Superman says, "THAT'S my greatest strength!"
MINOR:
There are a few minor moments throughout the film where flying characters crash into other flying characters from out of frame, but these moments happen during exciting scenes so they're unlikely to be startling.

It happens about 1 hour and 38 minutes in. Superman is covered in nanites and after falling from space crawls out of a hole and pulls them from his mouth. Not actual sick but still gross. It’s over by 1:39.
***small spoiler***
The dog is captured (this scene was probably the hardest), then saved.
