Kurt pulled up into Blaine's driveway and sent him a text to let him know he was there. It was too cold to get out and ring the doorbell. Blaine replied a minute later and told him to come inside. Kurt sighed and turned off his car. The door to his house was unlocked, so he went on in.

"Blaine?" he called. "Are you ready to go?" Kurt heard something upstairs, so he went up to see what was going on. Blaine was in his sister's room, sitting on her bed with her.

"Kurt's here," Sydney said, pointing at him. Blaine turned around to face him.

"Hey," he said. "I don't think I can go to the movie today. My parents left for a wedding in Cleveland, and Sydney got sick and I don't think I can leave her alone." Kurt frowned. He was looking forward to going out with him.

"It's okay," he sighed. "I understand. I'll see you later."

"No, Kurt, stay!" Sydney cried. Blaine's little sister was eleven years old and absolutely loved Kurt. Kurt smiled at her and sat down in between her and Blaine.

"You don't have to stay here," Blaine told him quietly. "I don't want you catching whatever she has." Kurt patted his knee reassuringly.

"I'm fine," he promised. "I never get sick. I can help you take care of her. It'll be like babysitting." Kurt had never babysat before, but it couldn't be too hard.

"I want to go downstairs," Sydney said, crossing her arms. She was just like Blaine when he was sick- demanding and grumpy.

"You just said you wanted to come up here," Blaine argued.

"Yeah, but now Kurt's here," she fired back. "I want to watch TV with him." Blaine sighed, and Sydney dragged Kurt by the hand as they walked down the stairs. "I want to watch Dance Moms with you. I have three episodes to catch up on."

"Okay," Kurt agreed when she finally took a breath. He kicked his shoes off and sat next to her on the couch. Blaine made her soup to eat and made her take medicine. She didn't seem all that sick to Kurt, and he told Blaine that in the kitchen.

"Yeah, she threw up on me and said she felt better," Blaine grumbled. "I took a shower for forty-five minutes and I still feel nasty." Kurt frowned.

"It's not her fault," he defended. "Come on, let's watch TV with her." Blaine sighed and followed him into the living room.

"Kurt, can you stay all day? You take better care of me than Blaine," Sydney whined. He was surprised to hear that, and laughed a little bit.

"I'll stay here for a while," he promised.

"Blaine, I need cough drops," Sydney ordered. "The cherry ones. My throat hurts."

"You used them all up," he told her. "I'll go get more, I guess. Do you need anything else?" Sydney shook her head, and Blaine grabbed his car keys and turned to Kurt. "Do you want to come?"

"No, I'll stay here with her. We'll be fine. You go on," he said, waving him off. Blaine shook his head, half-teasing, and left.

Kurt wasn't sure what to expect taking care of a sick kid, but it proved to be pretty easy. Sydney just leaned up against him and watched TV quietly. After Blaine had been gone half an hour, Kurt debated calling him, but they were doing just fine.

"Kurt," she peeped finally as the show was ending. "Kurt?"

"Hmm?" he looked down at her. She didn't look good, and she was breathing quickly. "What's wrong?"

Sydney pressed her hand over her mouth, and her long brown hair fell in front of her face. Kurt didn't know what to do. He'd never had to deal with that sort of thing.

"Oh! Oh, dear. Um, it's okay. Here, come here," he stammered, trying to act quickly. He didn't want her puking on him the way she did to Blaine.

So much happened at once. Blaine came through the front door, and Sydney leaned forward and got sick on herself. Blaine dropped the grocery sacks he was carrying and hurried over to her. Kurt wasn't sure what to do. He felt bad for not acting fast enough.

"Whoa, you're okay," Blaine said to her, brushing her hair out of her face. "It's okay, just breathe." She was wearing several layers of clothes, so Blaine took off her hoodie. Kurt stood there helplessly as Blaine got her some water from the kitchen. "Drink all of that. I'll bring you some soup and crackers to eat. That'll help." Kurt sat down next to her again awkwardly.

"Sorry," Sydney mumbled. "Sorry I almost puked on you." Kurt smiled.

"You're fine," he assured her. "Me and Blaine will take care of you. Sound good?" Sydney nodded, and turned on another episode of Dance Moms.

Author's Notes:

Oh dear Kurt he's so awkward with kids. Imagine if he had younger siblings. I hope you like Blaine's sister! She's my first original character to use in fanfiction.
