Batman x child! Reader 3

        Your (e/c) eyes opened the next morning. After Bruce told you he was going to adopt you, he decided it was best for you to get more sleep. You agreed, still happy you were getting adopted. Your room was nothing special. At least in Bruce's eyes. But, to you, it was special. A soft bed, a huge closet, a desk and a few dressers. Plus, the room was your favorite color. This was special. You climbed out of bed, your feet making a light thud on the floorboards. You ran quickly downstairs, wanting to see your dad. You looked in the living room for him. 'Nope. Not here. Maybe the kitchen' you thought, hoping to find Bruce. You went into the kitchen and heard two voices talking. One was Alfred and the other one was a young boys voice. You walked towards the table, rubbing sleep from your eyes. "Ah. Good morning, (y/n). Did you sleep well?" Alfred asked, smiling politely at you. You nodded and went to your chair at the table. But, in your chair, sat the young boy. In your chair, not his, yours. You looked up at him. He looked around twelve and had black hair. He smiled down at you. "Hello. You must be -" "You're in my chair." You mumbled, cutting him off. He glanced up at Alfred, then looked back at you. "Uh. What do you mean?" You pointed to the chair. "I sat there last night and claimed it as my chair. You're sitting in my chair." Your (e/c) stared up at him, waiting for him to get out of the chair. The boy stayed still for a moment before he got out of your chair and went to the chair next to it. A smile came across your (s/c) face as you climbed onto your chair. "Thank you", you said, happy you had your chair. "Who are you?" you asked, tilting your head at the boy. He smiled at you. "I'm Richard Grayson. And your (y/n) right?" You nodded your head. Richard smiled at you. "Oh. That means you're my little sister." You looked at him confused. "Huh?" Alfred sat at the table across from Richard. "Master Wayne has also adopted Mr. Grayson. So, he is technically your brother." You looked at Richard who was nodding. You smiled at him, happy that you had an older brother. You turned to Alfred. "Where's dad at?" Alfred smiled at you. "He's out, filling out your adoption papers. He should be home soon." You nodded excitedly, wanting Bruce to be home soon. 
            You climbed out of your chair and wandered around the kitchen. 'Where's the flour?' You spotted the cabinet where you found the flour the last time. You hopped on the counter and opened the cabinet. Smiling evilly, you began to reach for the flour. Until, you were picked up off the counter by Alfred. "Now now. Don't go making more messes. Here, you and Master Grayson can go run around the garden until Master Wayne comes home." You frowned and walked over to Richard, who was standing by the table. You kept pouting and then walked into the living room. Richard followed you, thinking your pouting was cute. "You don't want to see the garden?" he asked. You shrugged, keeping silent. "Wanna piggyback ride?" You nodded and turned to Richard. He motioned you over and kneeled down. "Alright. Get on." You hopped onto Richard back and smiled. "Go piggy." He laughed and carried you outside. You looked around the garden. It was beautiful. There was a huge variety of flowers and trees that were placed in rows. Richard set you down and you looked around the garden in amazement. Richard smiled at your wide eyes. Before he could talk to you, you ran down one of the rows of flowers and stopped when you spotted (your favorite flower). Richard jogged after you and saw you attempting to get one of the flowers. You, however, couldn't get the flower since it seemed like it was fighting with you. You frowned and stopped pulling on the flower. Richard held in a laugh and sighed. "Do you want me to get the flower?" You nodded, angry at the flowers. Richard picked the flower, making it seem easy. He handed you the flower and you happily took it. "Thank you, big brother" you said, looking down at the flower. Richard smiled widely, happy he was called big brother. You placed the flower in your (h/c) hair and poked Richard. You then took off running, yelling "You're it!" Richard sighed and started to run after you. You made your way into the house after attempting to lose Richard in the garden. You giggled and closed the garden door before running again. You ran into the living room and shrieked when you were picked up.
        "Hey hey. Calm down. I didn't mean to scare you," Bruce said. You smiled at the voice and hugged him. He hugged you back. "Why were you running?" You giggled. "Me and big brother were playing tag until you got back." He nodded and looked around for Richard. "Where is he?" You shrugged. "I don't know. Maybe still outside."  Bruce set you down on the floor and went to go find Richard. You followed by his side, holding his hand. Bruce opened the door to the garden and looked around. "Richard?" No response. Bruce looked down at you. "Are you sure he was outside.?" You nodded. "Yeah. Unless he came inside some other way. Like a window on the second floor", you joked. "Wouldn't doubt it" Bruce replied. You looked up at him. "What?" He shook his head. "Ill tell you later," he said, leading you towards the living room. You frowned, wondering what he meant. That was until you heard a loud thud from upstairs. "Something happened upstairs", you said, pointing at the ceiling. Bruce nodded and sighed. "Richards inside now. Go tell Alfred I'm home. Ill get Richard." You let go of Bruce's hand and walked to the living room, where Alfred was dusting a bookshelf. "Dads home," you said happily. Alfred turned around and looked at you. "Where is he then?" You pointed to the staircase. "Upstairs." Alfred nodded and went back to dusting. You laid on the floor and stared up at the ceiling. A few seconds later, you heard Bruce and Richard walk down the stairs. You looked at Richard when he laid by you. "How'd you get inside?" Richard smiled at you. "From an upstairs window." Your (e/c) eyes widened. "I was right," you yelled out proudly. Bruce chuckled and sat down on the couch. You quickly got up and sat by Bruce. He patted your head. "All the paperwork is done. You're a part of this family now." You smiled happily and hugged Bruce tightly. "Thank you", you squeaked out. You now have a dad, an older brother and a rocking butler. What more could you ask for?
