Another awesome inspiration from the amazing fic of @thegraytigress’ The Domestic Life of Mr. & Mrs. Rogers - “Big Brother”
James couldn't stop staring at the bundle against Mommy's chest. It was a little face with dark hair and scrunched up lips. The baby's eyes were closed. His little fingers were curled around the edge of the blanket. "He's so tiny."
"Yeah," Daddy said softly, crouching beside him. "That's why we all have to be careful around him."
..."Can I hold him, Mommy?"
"Of course you can, baby," Mommy said with a smile.
"I'm not the baby," James said proudly as Daddy wiped his hands with sanitizer. "I'm the big boy." Daddy laughed. Mommy did, too. "You are," she agreed...
James looked down. The baby gurgled in his arms and made a bunch of soft, strange sounds. This was weird, too, but it felt alright. It felt good. And he was warm and happy, being there with his parents. "What's his name?" That had been something everyone had talked about. The baby's name.
"Joseph," Mommy said.
James liked that, too. "Can I call him Joe?"
Daddy smiled. "Sure, you can."
James looked down again. "Hi, Joe. I'm James. I'm your brother."
"Big brother," Uncle Bucky reminded with a sly grin.
"Yeah," James said, grinning proudly himself. "I'm your big brother. And it's my job to take care of you."
