(This chapter is for anyone reading this that is a little, or anyone who is curious about it, I am a little and I read a lot of x reader preferences and barely any of them have chapters for littles, if you are uncomfortable with the little lifestyle then just skip the little chapters, I don't need random people who know nothing about this lifestyle making fun of it or making other littles feel worse)

Tony Stark: You knew that you would have to tell Tony at some point, you also wanted to ask him to be your caregiver officially because you trusted him completely and knew that he would be a great caregiver. So one day you two were just hanging out and you thought it was the perfect time to tell him. You calmly asked him to sit down because you needed to tell him something. He got a bit scared hearing that you needed to tell him something and how serious you sounded but he still sat down and took this conversation very seriously. Once he sat down you sat down across from him and told him, and to your surprise he took it very well. You did have to explain it but you expected that. After you finished explaining you asked him if he would be your caregiver and he said yes.

Bruce Banner: You and Bruce didn't get a lot of alone time but when you did you spent it together getting to know each other so on the night of your two year anniversary you decided that you could tell him about being a little. You also knew that you could trust him. So you planned a nice dinner and sent him out to get wine. He agreed and quickly kissed you and then left. You started cooking and while you were cooking you started to practice what you were gonna say. When you finished cooking you started to set the table but you were still practicing what you were gonna say. "Ugh! I can't tell him this..." you sighed and sat down and put your head in your hands. "Can't tell who what dear?" You heard Bruce ask from behind you which made you look at him and start studdering. He stopped you and told you to breathe and then calmly tell him what was going on. Once you had calmed down a bit you told him. He didn't know what you were talking about so you did have to explain it to him but once you did he decided to do some more research on it then he completely understood it and offered to be your caregiver, he also asked what happened to make you have to do this.

Bucky Barnes: You had just gotten Bucky back. Your Bucky, he remembered everything and everything was going great but Bucky could tell you were hiding something from him. He wanted to know what was going on but whenever he tried bringing it up you would derail it and started talking about something else. Finally he figured you wouldn't tell him yourself so one day he waited till you were gone and he went through some of your stuff until he found a dolled up box which he hadn't seen before he sighed and opened it and found a bunch of baby stuff like pacifiers, sippy cups, and stuffed animals. He figured that this was some old stuff from when Mary was little so he didn't think much of it and closed the box putting it back away. Two weeks passed by and he still didn't know what you were hiding from him. He came home one morning from a run with your brother and went to take a shower but when he opened the door he saw you in a bubble bath sucking on a pacifier and little toys that a kid would use. He looked at you confused and you looked at him shocked and quickly took yourself out of littlespace. He closed the door and sat on th ledge of the tub and gestured for you to explain. Once you finished you looked down thinking he wouldn't want to be with you anymore. He thought for a moment and smiled softly and kissed your head and said "hey look at me." You looked up at him and he smiled more "I love you no matter what...also you could've told me this sooner." He said. You smiled and hugged him he smiled and hugged back. "Hey babydoll, want me to help you with your bath?" He asked smiling softly and you nodded. "Yes please." You slipped back into littlespace.

Pietro Maximoff: You knew Pietro would find out about sooner or later but you were scared of how he would react to it. You decided to be upfront with him. You took him out to the park and lead him around the lake. "Princessa, what's going on?" He finally stopped the two of you and asked. "What do you mean?" You tilted your head. "Something is wrong, I can tell....you've been so nervous and stand offish lately, you're not telling me something and I know it, so what is going on?" He asks and crosses his arms. You sighed and started explaining and when you finished you looked down and bit your lip. He smiled softly and kissed your head "Princessa..." He lifts your head to make him look at him. "It's ok. You don't need to hide stuff like this from me." He cuped your cheek and smiled more. "I absolutely love you." He said softly. You smiled and hugged him which made him hug back. "I love you too." You said.

Loki Laufison/Odinson: Loki knew you were hiding something he didn't know what it was but he knew something was up so he tried to ask you about it but you didn't tell him. He figured with as stubborn as you were he wouldn't be able to get it out of you so he devised a plan. He went down to your lab and locked both yourself and himself in so that you couldn't get out and no one could get in. He asked you what you were hiding and before you answered he started reading your mind so that when you did answer he would be able to tell the truth. You said you weren't hiding anything but in your head you were thinking what you wanted to say to him. He rose a brow at you. "Loki I know you're in my head....you aren't that slick." You crossed your arms. "Why didn't you tell me earlier? This could've been easily avoided." He smirked and kissed your head. "I know....I just....I was scared that you wouldn't want to be with me anymore." You sighed. "Oh darling, this is not something that I would break up with you over....I love you so much." He smiled and wrapped his arms around you. You looked down and played with the collar of his black button up shirt. "I love you too." You smiled softly.

Thor Odinson: You and Thor had made a house for the two of you on the border of new Asgard. You two spent so much time together. One day you had to go out for some food. Thor stayed home and he dropped something under the bed and went to pick it up but he also saw a box that he didn't remember so he took it out and opened it going through it. He saw all this baby stuff. It confused him so when you got home he brought it up. You froze at the mention of it. You sighed and explained it. Thor sat and listened then smiled once you were done and told you that you could've told him sooner and that it didn't matter to him he still absolutely adored you.

Natasha Romanoff: You had planned to tell Nat yourself but she's a spy who has known you for years....she picked up on the signals and put two and two together and brought it up to you which kinda scared you. She didn't seem to mind it. You asked if it was ok with her she smiled softly and nodded saying it was perfectly fine and that she didn't care and would do anything to help you feel comfortable. You asked if she would be your caregiver and she said yes.

Wanda Maximoff: You knew that you had to tell her at some point and so you decided that you were just going to tell her. You asked her to come down to your lab so you could talk to her about something. She agreed and went there after breakfast. She found you in the room listening to music. She smiled and tapped your shoulder which made you jump slightly and turn. She smiled softly at you and you smiled back nervously then looked down. "What did you need to tell me?" She tilted her head. You started to explain everything. When you finished you looked back up at her. "Oh honey...I already knew that." She giggled softly. "Wait, what?" You asked confused. "Yeah....you seemed very uncomfortable with something so I read your mind to find out if I could help...I'm sorry." She bit her lip softly. "No, no, no, don't apologize....I appreciate the help." You smiled and hugged her. She hugged back and kissed your head.

Peter Parker: You knew that you had to tell Peter. Little did you know he already knew, he wasn't trying to spy on you it just happened. He had just finished his rounds and had stopped by your place to say goodnight. Wen he stopped by your window he saw you while you were in littlespace. He sat there and watched for a bit. He then realized he needed to get home. When he got home he looked up the behavior and found the littlespace community and did the research on it. He then texted you about it. When he saw that you read the text and didn't answer he called you. You answered the call knowing that you had to. He asked you about it and you explained it. He listened to you. When you finished he asked if you trusted him. You said yes. He smiled and asked to be your caregiver.

Clint Barton: You knew that you were going to need to tell him at some point. You invited him over. When he got there you sat him down and explained  it to him. He didn't quite understand so you had to explain it more. He finally understood and told you that he didn't care and that you were still you and that he'd love you no matter what.

Nick Fury: You didn't think that it would be in you file but it was so when Nick read it he found that out and brought it up to you when y'all started dating. You explained it to him and when you finished he shrugged and asked if there was anything that he could do. You told him about caregivers. He agreed to be yours.

Steve Rogers: you knew that you would have to tell Steve everything eventually so you asked him to come over to your apartment. One he got there you told him to sit down and he did. He asked you what was going on you sat down across from him and explained it. Once you finished he chuckled softly and told you he already knew that. When you asked how he knew. He told you he figured it out after when he woke up from the ice, he also said he already considered himself your caregiver.

Sam Wilson: You are in the army, Sam knew what that came with when he started dating you. He knew about the nightmares, and the reaction to noises that were like gunfire, he knew how some modes of transportation would affect you. He also knew that you would need a way to cope with all that. He wanted to know how you coped so that if he saw you doing it he could help. So he went to your apartment one day unannounced and spent time with you. When he finally asked you about your coping mechanism you told him very simply and calmly. When he asked what you ment because he didn't understand what littles were you explained it. He then nodded and shrugged asking if there was anyway to help when you were in littlespace. You told him about caregivers and he said he'd be yours.
