Lucifer

He would be very confused about the sensation he feels from y/n once they're pregnant. He would get stressed about it so much that he might take days off only to figure it out. And won't let y/n out of sight, even going to the toilet with her and standing outside the door. Always holding hands, always by him. Would lock door to his room during the night and hold her tight in bed. He would feel that it's something important that's happening, but wouldn't be able to tell why, which would be scary to him.

Once he figures it out, or y/n does a pregnancy test he would finally calm down a bit, but there would be lots of cuddles in his room afterwards, especially with her belly, even while it's still flat. Lucifer would get so excited he'd immediately start browsing about pregnancy, buy everything that would be necessary for the pregnancy and would count down days, worrying about it more and more as it would go closer to the delivery.

A big "NO" to going out without him even if one of his brothers are accompanying. He would rather drop everything and go where she wants than let her go without him.

Touching her belly every day every few hours to check how is the baby doing and praising her for doing good even if she didn't do anything at all. If something is off, then y/n would immediately end up carried by him to the bed and taken care of.

Lots of kisses from Lucifer. Even more than before y/n got pregnant.

Daily massage and bellyrubs.

Y/n would always be dressed warm enough but not too much to not sweat.

Lucifer would be preparing the most relaxing baths for y/n, would sit in the bathroom till she gets enough of the bath, would wash her by himself and carry back to their shared room.

Mammon

Poor y/n would get a panicked yelling from Mammon once he feels something is off with her. He would ask her a million of questions about what was she doing, what is she feeling and what could be happening. He would get strict with her to the point that she might want to yell back at him. He would absolutely not leave her alone, even if she'd make him mad. He would be following like a shadow wherever she goes. He could also get self-conscious and ask if she was spending time with other demons lately, but that's just his worry playing tricks on him.

Once Mammon figures it out he would literally bawl his eyes out, jumping, hugging everyone, especially y/n of course, run to the shops to get everything y/n might need for pregnancy and even get some baby toys in advance. He would immediately search for the online job to provide her everything she could ever need and might even end up overworking a few times. He would start cooing to her belly since the very start.

Just like Lucifer, Mammon wouldn't let y/n go anywhere without him. He would list lots of things that might happen from "you could get a callus" to "the meteor might fall onto you" to prove that he absolute needs to accompany her.

He would love to stroke her belly up and down in the gentlest touch possible and keep it warm all the time. He would come and put his hand on it and if he thinks it's too cool, he would bring a heating pad or put her in bed and tuck her in, commanding her to stay and get warm. Would also bring her warm drinks only. If she'd ask for cold drinks he would make sure there's no ice and it's not too cold for her.

Would be coming up with names for the baby from the first day but wouldn't be able to pick one to the very end.

Mammon would try and cook for her. He might mess up some dishes because of the anxiety, but who knows, maybe that's actually what she would like right now.

Mammon would 100% do watermelon challenge to at least have an understanding how hard it is for y/n to live with a belly in front of her. After the challenge would be even more attentive.

Leviathan

Would lock y/n with his tail before he figures out what's going on with her. He could sit and play games on autopilot with her sitting between his legs, his chin on her shoulder or her head, but he wouldn't actually think about the game at the moment. He would sit and try to focus on the feeling, only letting her go for two minutes and no more. If she won't return by the timer he would pause the game and rush to search for her.

Levi would 100% turn into a tomato, go hysterical and black out once he'd learn that y/n is pregnant. He'd ask Karasu AI assistant a million of questions about pregnancy and order tons of necessary and unnecessary things online. Would end up broke by the end of the day and could even consider selling some of his game accounts, items or merch to absolutely be able to buy everything she needs. Or could work as a booster for others and level up other people's accounts for money.

Would get a legit bed instead of a bathtub so y/n is comfortable. While sleeping with her, Levi would curl his tail around her waist or around her belly, keeping it warm and comfortable. Would always ask her if she's hungry, cold, sleepy or feels unwell. Would try to be strict, but wouldn't be able to act like this for too long so he'd end up being the softest he could ever be.

Could accidentally let her go somewhere alone if he's too focused on something but after a while would be BOLTING to find her, then apologize a million times almost in tears.

Levi would love to lay his head on her belly and get his head gently scratched. It would calm him down as he would know that his partner and his future baby are feeling good.

Always standing a step in front of her whenever talking to anyone, even his brothers and would wrap his arm and tail around her if he would feel anyone approaching from behind. Possessive 🫢

Would absolutely draw something silly, cute or anime themed on her belly once in a while to make her laugh.

Satan

Satan would likely be suspecting that what he feels is y/n's pregnancy, but wouldn't point it out not to scare her, because he'd be uncertain about it. But it wouldn't stop him from acting protective. He would stop her whenever she's about to go somewhere to check her temperature, blood pressure, her clothes and shoes. Letting her go alone would be scary for him, but he would try and let her have freedom with him calling her every half an hour to ask if everything is okay.

Once he'd learn about the pregnancy, he'd be lifting y/n while hugging and spinning her a bit, jumping and rub their cheeks and noses together, giving lots of kisses to her face. He would immediately research about previous hybrid pregnancies to be prepared for anything that might come. And he would 100% buy some cute cat themed clothes for the future baby, crying from his own imagination of the future kid wearing it.

Satan would buy tons of books about pregnancy and women's health and literally become her doctor. He might even consider offering her to give birth at home in the bathtub and be the one who would be helping to deliver the baby.

One sigh, cough, sneeze or other little noise and Satan would be right there asking if something happened to y/n, checking the baby's wellbeing, checking her temperature, eyes and pulse. Would always put his forehead onto hers to check her temperature.

If y/n has long hair Satan would braid it in the most comfortable way possible so she could move her head freely, sit and lay comfortably with it and forget that she even has long hair.

Satan would always support her about her looks and explain whatever happens to her in scientific language. He would give more love to the spots she's insecure about, touching them in a loving way, kissing them and telling everything about why he loves those spots.

Would call her "kitty mama" affectionately.

Would coo to her belly once it's round and read fairytales to it in a calming voice that would more likely make y/n fall asleep instead.

Carrying y/n around for absolutely no reason.

Asmodeus

He knows what's going on inside y/n and tells her instantly. Maybe he would cutely apologize for causing it.

Once they confirm that y/n is indeed pregnant he'd prepare everything that would make her comfortable during pregnancy and buy a bunch of skincare products for pregnancy. Cravings, massage, care and love - he's ready to give it all to her. And of course he would anticipate the gender reveal to get cute clothes for his kid.

Asmo would research the internet about it and ask his fans about anything that would bother him about y/n during pregnancy. Any little symptom would get searched and asked about. And just like Satan Asmo would try to convince y/n to give birth at home. He would search for the best doctor to help y/n with that.

He'd LOVE to search for the perfumes that would smell good and not cause y/n nausea for both of them.

Belly massage by the most gentle hands and soft talking to the little one inside of it. Asmo would enjoy this time as much as he could and try to make it enjoyable for y/n as well.

He would style y/n's hair and clothes in a sweet way so she looks radiant and comfy. He could develop a new hobby and design clothes that are comfortable and sweet for pregnant people thanks to y/n.

Would definitely paint something on y/n's belly sometime.

Always by her side. Even if he looks friendly and lets y/n choose who would she trust to step closer, he'd still be watching her closely and punch anyone who oversteps it.

Would help her to do exercises for pregnant and make sure she's feeling okay after every session, reminding her to drink plenty of water.

Even more kisses from Asmopapa than before.

He would talk to y/n's belly sweetly, telling the baby how much he loves them already and give them smooches.

Beelzebub

He wouldn't understand what's happening once he feels different things from y/n, but he would feel uncharacteristically overprotective and could get possessive up to the point of holding y/n close to himself in public.

Once he learns about the pregnancy he would get extremely happy, squeezing y/n in his hug tightly, then getting worried that he squeezed her too much and getting panicked over it right before he would decide to raid the grocery stores and get EVERYTHING in case y/n craves it.

Would cook A LOT of food to make sure y/n is never hungry but would forget about his own hunger in the process so Beelzedaddy needs some reminders about his empty stomach.

Would try his best to stay beside y/n all the time and if she goes somewhere without him, he would get either strict or sulky, depending on situation. He's so worried that y/n could faint or get too hungry. After all it's his child growing inside her.

He would be loving y/n even more once her belly grows prominent. Beel would stroke it everytime he can, loving the fact that y/n bears a new life inside her and that this new life is his child as well. He would feel everytime it gets bigger and notice it to her. And he would definitely love to approach from behind and hug her, placing his hands onto her belly, lifting it up gently to get some weight off her.

Would only allow her to do exercises for pregnant people under his instructions and nothing more. He's too worried to make her hurt herself.

If she'd have weird cravings he would try to fulfill them and then try them out himself because he's up to something new to eat. He would even make a small recipe book.

He would always stay close to her in bed. Even if it's hot in the room he would still try and stick close.

He would carry y/n around whenever she's having any pains or whenever he wants it. He just loves to carry her around.

He would prefer to listen to her belly than to talk to it. Sometimes he would even fall asleep while laying his head on it.

Belphegor

Belphegor wouldn't be able to sleep normally whenever he would feel that something is up with y/n. He would be more irritated than usual and would get strict with y/n, grumbling anytime she goes anywhere he doesn't want her to go. He wouldn't even let his brothers touch her.

Once he learns about the pregnancy he would appear lost in thoughts most of the time. He would be thinking about many things from simple, such as getting a pillow for pregnancy and comfortable clothes, to the complex ones about if he should work harder for her or stay near her instead.

If one of his brothers oversteps her boundaries about physical contact, he would dig a grave for them in a second and get her back to their blanket nest at home.

Ah yes, blanket nest... He would build a nest for her to stay at whenever she needs to feel comfortable and warm at their shared house. Blankets, pillows, even bathrobes would go into the building. He would also build a curtain above it so it's all snuggly inside for y/n. And he would of course crawl in to cuddle her every night.

While cuddling y/n, Belphie would always make sure she's warm and covered in blankets, especially her belly. He might accidentally overdo it and make her sweat sometimes and would have to take care of it before she cools down and catches a cold.

He wouldn't go anywhere without her and let her go anywhere without him. He's too possessive to let anyone close, especially during this delicate time. If you'd see him glaring at you, step back because he's about to strike you down.

He's the gentliest in care. Even if y/n would have a meltdown he would talk to her softly, give her hugs, kisses and solve whatever happened for her. He would never see it as a problem, rather a little inconvenience she is facing and he needs to solve. That would only boost his self-esteem as a man and as a husband.

Would gently massage her legs and belly sometimes even if nothing hurts and sing lullabies for her and the baby inside. Soft talking and kisses are his favorite things to do to her pregnant belly.

Diavolo

He knows what it is immediately, but he's too caring to immediately announce it to y/n. He knows she could get nervous about it, so he would ask Barbatos for an advice about how to approach it better. But before he does he would make sure she doesn't wear anything that would press on her abdomen. No tight clothes anymore. Y/n could notice that he's a bit nervous. Diavolo can't hide his worry for too long after all.

He would find a way to tell her about the fact that she's pregnant gently and carefully and would reassure her about anything that might worry her all while keeping his nervous voice soft and caring. He would also vow to love and cherish their child no matter what, promising to not repeat his father's behavior.

He would sneak out from work while Barbatos isn't looking to spend time with y/n because Dia-papa worries a lot. He would as her a million of questions: if she ate, if it was enough, if the clothes are good, if she's thirsty, if she feels lonely, if she craves anything, if anything hurts. Even if y/n would actually feel okay, he would worry about her every second, because it's his woman and his child, who's he's responsible for. Plus he's scared that she could lose her life while delivering like his own mother did. He would do anything to prevent that even if it means neglecting his work.

The best bedroom is hers even if it's his bedroom. He would let her choose if she wants to share the bed or if she wants to stay alone in her room, but whatever she would choose, he'd move to the next room to rush to her if something happens. But of course he would ask her if he could stay with her.

In public he would not let her go anywhere far from him or Barbatos. If he's busy, he would ask Barbatos to stay with her. If he can stay with her, he would. No getting from his sight.

Diavolo is going to order clothes that would fit her perfectly instead of buying clothes. Even underwear would be specifically made for her to let her feel comfortable during the pregnancy.

If y/n would ever have a meltdown, Diavolo would be cooing at her, holding her in his arms and slowly rocking her from side to side like a baby while talking to her softly and trying to resolve the issue. Forehead, nose and cheek kisses are required during those times.

Diavolo would find the best doctor for her and if he ever sees or feels that they'll doing something against her health, the person would be dealth with immediately. He knows many demons try and push him off his throne so he would be careful around those who are working with his unborn heir.

Diavolo would call y/n beautiful everyday, knowing how much it takes for a woman to create a life. He would treat her like a goddess and everytime her body changes he would shower her in love even more.

Barbatos

He would know about it immediately as well as Diavolo. He'd be hesitant about looking through the possibilities of either of the outcomes. He wouldn't be able to chose if he should tell y/n or to let her figure it out on her own.

Once y/n knows about it he would ask Diavolo for less working hours to spend more time with y/n. He would go to get her everything she needs for the pregnancy and spend some time in his room to see and prevent anything that might happen to the child, leading the timeline to the perfect route from the very start.

Barbatos would make tea mixes for everything that might happen to y/n during the pregnancy from the mild symptoms to the most irritating ones. Yes, he chooses the best route of the timeline, but sometimes the best doesn't mean the easiest...

Gentle kisses and massages plus himself as her doctor. He would learn everything about pregnancy, kids and everything related to that from both Devildom and human realm to make sure everything is going smoothly.

He would adore the pouty face she would make whenever she craves something to eat and would love it even more to fulfill her requests even if they're weird. He would definitely call her naughty for that, lovingly, of course.

Sometimes when exhaustion is taking over he would lay his ear down onto her belly and fall asleep while listening to the sounds of their child.

He would let her talk to others and interact with them, but his eyes would always stay on her. If something happens, he would immediately appear right beside her and solve it. Violently sometimes.

Barb would stare at her for several seconds when she would walk by or sit somewhere beside him. He'd just love to realize that his long life lead him to such a big happiness so he would enjoy it to the fullest.

Even during her pregnancy he would sometimes try and get her laid. Though would probably get laid himself instead. Not that he's against it. It's still his woman after all.

Barbatos would love to lock her in his arms using his tail. Sometimes he would tickle her belly with his tail as well for the sake of giggles.
