The Baby Assignment [Lucifer]
I have a list of actual headcanons for demon baby behaviors, but this is not that post.
You and the boys have a baby! (sort of).
You should’ve never told Diavolo about how high schools used to have practice baby classes.
Note: most of the genders and children come from “The Bros as Dads” post.
Cut me some slack on the names. I didn’t really have them planned, haha.
Lucifer:
Extremely skeptical. This whole assignment depends on you two standing in a summoning circle and--in a flash of light there’s a KID in the middle of the floor.
It’s a GIRL!
This triggers his demon form on reflex because he’s startled and can’t help but have flashbacks of Lilith. You’re cooing to the little girl and Lucifer feels breathless as he takes in her hair (it’s his) and those big eyes (they’re yours)
His wings flap a few times before pressing close to his body. This has caught the baby’s attention and she’s staring at him with more intelligence than a child should have.
The professor says the child will grow exponentially over the next week or so and she should be able to deliver a report on how competent you are as parents. Their developmental age will be assessed and factored in as part of the grade.
You walk carefully over to Lucifer, eyes shining and a tiny fist in your hand and oh Diavolo, he wants this child to be real right then and there!
The naming doesn’t happen until you’re back at the House of Lamentation with a massive magical trunk that will spawn child necessities. You sit in his study as the baby looks around and points to things. You name them off.
You’re in the middle of walking her over to look at his records and watching her slap things on the shelf, trying to feel them with her fingers, when he gets the idea to name her after one of the human composers he knows (”Marianna.”)
You honestly thought the addition of a literal child would throw Lucifer off but he’s prepared. It’s only then you realize he’s been alive for thousands of years and helped raise the other six people in the house
Enjoy your view of Lucifer wearing a baby sling for the first three days because unless you have a real kid together, this is the only time you’ll see it
The two of you work on a schedule and carve out time to teach the child on top of your other duties. Sometimes you’re hooked up to the sling, sometimes it’s him. He gets a kick out of seeing you tote the kid around and usually catches you tickling her feet.
Diavolo graciously lightens up on Lucifer’s paperwork load (BY A LOT!) in exchange for seeing the child and playing with them
Most of her facial expressions take after Lucifer’s and Diavolo is BEYOND amused
After day 3, Marianna gets distressed seeing Lucifer sit so long, so she’ll toddle you to Lucifer and just points until you do something about it
100% a daddy’s girl and Lucifer has a hard time keeping his pride in check. It’s coming off of him in waves
She says her first words between day 4 and day 5 and Lucifer wants to cry (he does) because the first one is “daddy”
From day 5 on it’s a constant fight to keep her close because the bros want to smother her for being so cute and are bugging her to say their names
Marianna is partial to Satan and Lucifer is secretly glad. Satan acts all smug about it.
She has Lucifer’s insistency for perfection. Mammon was messing with her tea party set up and she bit him for moving her plate in the wrong spot. That was day 6 and she had her pointy baby demon teeth. Marianna got a little whisper scolding that Mammon would’ve died for BECAUSE SHE GETS KISSES WHILE SHE’S GETTING SCOLDED? FOR REAL?! HE GETS STRUNG UPSIDE DOWN!
Marianna hates being fussed over and likes to dress herself. Whatever you or Lucifer fix, she undoes when your back is turned.
One of her favorite hobbies is sitting on Lucifer’s lap and practicing her handwriting. She also likes to brush his feathers. Marianna asks to sleep in them and will try to hide from you in them. The giggles give her away.
By day 7 she has the intelligence of (at least) a 6 year old and has velvety nubs for horns. You learned that demons like to rub their horns against hard surfaces (or loved ones) as scenting and for their growth.
She accidentally scratches you up, not quite understanding you’re human, and goes into an absolute meltdown. She didn’t mean to hurt you.
Goes into a freaking rage when anyone tries to fix you up. Wants to do it herself. This kid is a literal puddle of apologies, please hold her.
She cuddles you for the rest of that day and officially gets her own little desk beside Lucifer on day 8. Marianna pretends to write her own letters but mostly draws. Bugs Lucifer with the random stuff Satan and Levi teaches her but he doesn’t mind.
You’d bring them snacks every now and then and sometimes you’d hear them singing together (ever so quietly). You didn’t know Lucifer could sing.
Lucifer has woken up with a fist in his face, accidentally been punched in the eye, and has been kicked away at least once since she was big enough to sleep in the bed. She takes after Lucifer in the way that she needs you behind closed doors. Marianna doesn’t sleep unless she can feel both of you next to her.
Lucifer officially has bragging rights about sleeping with you (even if he won’t pull that). Secretly gets the best sleep of his life. Really starting to feel the parent thing. A kid with you would be nice.
Marianna gets little fluffs for wings on day 9 and they “air box” when she’s angry. She demands back scratches for how dry and itchy the feel and you figure out she purrs like Lucifer.
She doesn’t always prank Lucifer but when she does, she hides his pens and makes him play hide and seek with her to get them back
Marianna likes to help out in the kitchen and loves setting the table. She gets mad if anyone messes with the napkin folds you guys practice. She makes a tiny Lucifer screech when Asmo gets obnoxious with taking pictures for Devilgram and Mammon nearly breaks his chair trying to run out of it. She laughs like you.
Around day 10 she insists on a family day and Lucifer has this sinking feeling in his gut that she knows she won’t be around much longer. Maybe it’s a side effect of the spell. The two of you spend the day running around the Devildom taking lots of pictures. Diavolo crashes a few of those pictures.
She spends day 11 burning the midnight oil with Lucifer. Around 9 PM he’s trying to send her to bed. Marianna just drags a blanket back into his study and snuggles down. He notices all her old pictures and some new ones she’s drawn. “It’s my book,” she tells him.
“Your book?”
“Yep.” she colors in the lines carefully, the finished pages pushed away and much better than her older ones. “It’s for you guys, for when I go away. And for your school.”
On day 12 you bring her back into the class, she’s dressed in similar colors to Lucifer. She wanted to look good for her presentation and she said ‘dad always looks nice’.
Marianna talks through her book, calling back memories of building blocks and playing hide and seek. She’s very proud of the pictures from two days ago. They’re her favorite. She shows off her horns and the “dad roar”.
You and Lucifer walk her to the circle. She stands in it as the spell determines her final age. She’s about 10, pushing the limits for growth as determined by the spell.
“I wasn’t here a long time, but I had fun.” she hands him the book and gives you a much longer hug than Lucifer. You wonder if it’s her way of apologizing for having a favorite even though she was good to both of you. “Maybe I’ll see you again sometime.” she looks up at Lucifer as she hugs him, her chin pressed into his stomach.
“Perhaps.” Lucifer takes on his demon form as the circle starts to glow, flapping one wing at her. She “air boxes” back before disappearing in a puff of smoke.
It’s a quiet, lonely silence. Very cold. There’s a subtle warmth in Lucifer’s embrace as he guides you back to your desk. It was brief, but you see why she likes his hugs.
