You and Loki were part of the Avengers so you lived in the Avengers tower with the rest of the Avengers. They left to go on a mission while you were left behind with Loki who was acting a little strange lately. He started wearing weird clothes, eating weird foods and you noticed he was shrinking his size. He also started talking weirdly, like a child, and in some occasions, like a baby. You thought it was just what he does but the shrinking made you worried. It was raining outside so you put on some warm clothes and walked to Loki's room.

"Hey Loki, are you hungry?" You asked as you entered his room. He was reading a book on his king-sized bed and was wearing a green button-up shirt that Tony gave him, some black jeans and green and black striped fuzzy socks that you thought was weird.

"Yes, I am. I would like some of that apple stuff." He commanded as if you were his own servant and he didn't even look at you.

You swear he sounded like a child sometimes.

"Oookaaay." You groaned softly as walked away from his room and headed to the kitchen.

"Hey, JARVIS." You said as you were finding the apple sauce Loki wanted.

"Yes, miss L/N? How may I help you?"

"Can you tell me if something weird happens with Loki? He's been acting weird lately."

"Yes, miss L/N. I will inform you if something happens, immediately."

You thanked Jarvis while finally finding the apple sauce.

A few moments past and you finished making Loki's apple sauce until Jarvis startled you a bit.

"I'm sorry to bother you Miss L/N, but Loki is suddenly smaller and more adorable than a few minutes ago."

"What are you talking about, Jarvis?" You asked, carrying Loki's bowl to his room.

"Well he's-" and before Jarvis was going to finish his sentence, you entered Loki's room and saw-

"A BABY?!?!?!" You finished his sentence and the baby giggled while clapping his little hands.

"Precisely," Jarvis said as you put down the bowl that was in your hands onto his dresser that was next to his door and walked to the cute little baby.

"Aww! Loki, you're so cute!" You cooed with the giggly baby cradled in your arms. You sat down on the bed and admire the little child in your arms.

He still had his beautiful emerald eyes and his silky black hair. His clothes turned into a green onesie but he had smaller green and black fuzzy socks. You realized that you had to take care of him and you didn't have a problem with that. You did a lot of babysitting so you have some experience with babies.

You heard his tummy rumble so you carried him to the dining room and made a baby chair with your magic. You set him down on the chair and went back to his room to grab his apple sauce. Right as you grabbed the bowl, you already hear Loki crying so you ran as fast as you could to him with the bowl of apple sauce in your hands.

Once you came to him, you quickly placed the bowl down on the table and tried to calm him down.

"Shh. It's okay. I'm here. Y/N's here. I'm not gonna leave you. Shh." You said softly, rubbing his back while hugging him. Once he was calm, you set him back down on his chair and used your magic to grab a spoon since you guessed that leaving Loki in a room alone would make him cry.

"Alright Loki, open up." You said as you grabbed a spoonful of applesauce and he opened his mouth wide.

You put it into his mouth and once he swallowed it, he giggles for more, almost spilling some applesauce out of his mouth. You giggled at his reaction and repeating the processes until there was no more left. You got Loki out of the chair and the chair vanished. You then heard thunder and Loki hugged you tightly. You grabbed the bowl and put it in the sink then carried Loki to your room and created a crib with your magic and set him down in it. Loki didn't let go of you and he started whimpering once he was in the crib. You sat down on your bed and waited for him to sleep

"Sugar!" He cooed reaching his arms to you through the bars of the crib and your heart melted at what he said.

Then the thunder started rumbling louder and Loki started crying while being in the corner of the crib, curled into a ball and you ran to him.

"Its okay, Loki! Shh! I won't let the thunder harm you. Not on my watch and Thor, if this is your idea, I swear..."

He started to calm down but he was still frightened so you sat down on your bed and placed Loki on your chest.

"Have you ever fed a lover with just your hands?" You started singing and Loki looked at you with his teary green orbs.

"Close your eyes and trust it, just trust it
Have you ever thrown a fist full of glitter in the air?
Have you ever looked fear in the face
And said I just don't care?" Loki seemed to calm down and started nuzzling his face on your chest.

"And it's only half past the point of no return

The tip of the iceberg
The sun before the burn
The thunder before the lightning
Breath before the phrase
Have you ever felt this way?" You sang while combing his hair with your fingers while you looked out the window that was covered with raindrops. You could see the lightning and the thunder started getting louder. Loki could hear the thunder too and curled into a ball while gripping your shirt with his little hands.

"Have you ever hated yourself for staring at the phone?
You're whole life waiting on the ring to prove you're not alone
Have you ever been touched so gently you had to cry?
Have you ever invited a stranger to come inside?

You're whole life waiting on the ring to prove you're not alone

Have you ever been touched so gently you had to cry?
Have you ever invited a stranger to come inside?" You sang loader so Loki wouldn't hear the thunder, holding his little hand and rubbing your thumb on the back of his hand. You started rocking him in the rhythm of the song.

"It's only half past the point of oblivion
The hourglass on the table
The walk before the run
The breath before the kiss
And the fear before the flames
Have you ever felt this way?" You could feel him shivering so you grabbed your blanket and covered Loki with it.

"There you are, sitting in the garden
Clutching my coffee,
Calling me sugar
You called me sugar"

"Y/N? Loki? Are you home?" You could hear the Avengers entering the living room but you didn't care and you didn't answer. All you cared about was that your baby Loki was calmed down and safe in your arms.

"Have you ever wished for an endless night?
Lassoed the moon and the stars and pulled that rope tight
Have you ever held your breath and asked yourself
Will it ever get better than tonight?
Tonight" 

Once you finished, you could hear Loki lightly breathing and the thunder seemed to end and saw the sunlight seeping through the dark clouds. You turned your head towards the door and you saw all of the Avengers standing in the doorway, looking amazed, especially Tony.

You signaled them to be quiet and got off the bed then placed Loki in the crib. Everyone looked at the baby then back at you. Everyone was confused but Thor seemed to understand.

"Good night, Loki." You whispered in Loki's ear and walked out the door with everyone else following behind you while giving you a look.

"What?" You said once you saw their looks and sat down on the couch.

"Did you have fun taking care of Baby Loki?" Natasha asked while sitting next to you.

"Actually yes. He was easy." You said and Thor looked amazed.

"When Loki was a baby, he was a nightmare! How was he easy?" He asked and you had no idea how to answer that.

"Well, he was very calm until I left him to go grab something and when he got scared of the thunder."

"He must seem to really like you," Steve said, sitting next to Natasha.

"How would you know?"

"Well, you said that he was scared when you left and you kept him company from the thunderstorm. You also made him fall asleep by singing. And we can all agree that you have a beautiful singing voice." Steve said and everyone nodded in agreement.

You blushed and explain what happened then you could hear a noise from your room.

You quickly got off the coach and everyone looked at you confused since you were the only one that heard the noise.

Once you entered your room, you could see baby Loki whimpering hugging a teddy bear you put in the crib.

"Hey, I'm here. Come here, sleepyhead," You said then grabbed him and carried him to the rest of the avengers. You could hear everyone awing at the baby boy in your arms. Loki was cuddling your chest still a bit sleepy with the teddy bear still in his hand.

"Well, would you look at that. Thor's jealous." Tony said and you saw Thor crossing his arms.

"Hey, Thor you wanna hold him?" You said and Thor lit up with a smile on his face. You walked over to him and gave Loki to Thor. Loki woke up but didn't do anything and Thor was smiling over him like a proud older brother.

"Bro!" Loki cooed and everyone was awing again. Your heart melted at the sight of them together.

"Hello, Loki," Thor said then he tickled his tummy, and Loki giggled.

"Aww, his first word!" Natasha squealed and you laughed.

"Actually he called me sugar earlier." You said blushing and Wanda squealed with Natasha.

"How adorable!" They said together and you blushed even more.

"Who else wants to hold Loki next?" You asked and Wanda rushed to you.

"Can I?" She asked trying to hold her excitement.

"Of course." You said grabbing Loki out of Thor's arms and Handing him to Wanda.

Everyone got to hold him and your heart was melting every time Loki was happy with them. Bruce was the last one and once he was through, Loki looked around to find you.

"Love!" He said and Bruce handed Loki to you.

"Awww!!!!!" Nat and Wanda squealed as you took Loki and set him on your lap.

"I love you too." You said then kissed his nose.

Once your lips touched his nose, you felt a lot of weight on your lap so you opened your eyes to see Loki as his normal self and you weren't kissing his nose. Instead, you were kissing his soft thin lips. You quickly broke the kiss and everyone looked at you and Loki.

"What's going on? Why am I on Y/n's lap?" Loki asked, still on your lap. You were too speechless to speak and you were red as a tomato.

"W-well you turned into a baby and then I had to take care of you and you got hungry and I fed you and you got scared of the thunder so you called me sugar and I sang you to sleep and when e-everyone came home, you were asleep and then you woke up and everyone got to hold you and then when you called me to love and reached for me then I grabbed you and said that I-" You stopped rambling realizing what you said earlier before Loki turned back to normal.

"T-then you said w-what?" Loki asked slightly blushing while getting off your lap to sit next to you.

"I-I said that I-I love you too and then kissed you on the nose and then you turned back to normal and we k-kissed on the lips." You said then shut your eyes closed in embarrassment.

You heard Loki lightly chuckling then felt his lips kiss yours. You opened your eyes wide open.

"Well I accept your confession, love." Loki whispered. You started to lean into him for a kiss and so was Loki but you both go interrupted but someone clearing their throat.

"Can you maybe do all this lovey dovey stuff somewhere else?" Steve asked blushing like crazy that his face was a bright red and you and Loki started blushing slightly.

"Of course, come darling." Loki said as he grabbed your hand started walking to his room.
