"Why do I not have any siblings?" Spock asked his mother one morning. A few weeks ago, he had turned eight, and a good number of his classmates had new brothers and sisters.

Amanda paused.

"Why do you ask?" she queried.

Loneliness around the house, wanting to be a mentor, not liking being the the only part-Vulcan in the universe. There were a lot of reasons.

"Curiosity," Spock stated.

"Well ..." Amanda started, "When I was pregnant with you, there were a lot of complications, and it was really hard not knowing whether things would turn out, so when you were born, your father and I decided that it would be best to just count our blessings and not try to have any more children."

"I apologize," Spock replied quietly.

"Oh, don't worry," his mother said quickly, putting her arms around him, "You were worth it."

Spock nodded, but he thought her logic was faulty. If having him was worth the challenges, so would having another baby.

"Do you ever wish you had a brother or sister?" she asked

"Sometimes," Spock admitted, "Some of my classmates have brought their baby siblings in for show and tell, and I kind of like them."

Amanda looked sad.

"Well you know what," she suggested, "If you like babies, Surlek has a new sister, and I bet his mom could use a pair of babysitters."

Spock didn't think this would be the same, but he replied,

"I will try that mother."

"Oh, and wait," Amanda said, "Let me give you some baking for his mother. And make sure you say 'Congratulations'."

*****

Surlek wasn't the brightest or the most personable boy, but he was Spock's best friend. He was tall and odd-looking and the kids made fun of him, but he was unwaveringly loyal, and never failed to stand up for Spock.

It was a few weeks before Surlek's mother allowed them to care for the baby. This didn't surprise Spock. Surlek was forgetful and easily distracted. Spock wasn't sure if he would trust him with a baby either.

"How did you convince her?" Spock asked.

"I do not know," Surelek replied, "For twenty-three days, I have asked her, and she said no, but today, she said 'Yes please' and gave her to me."

Surlek also had a bag with some diapers and a few boxes of vegetable juice. They walked to a playhouse that Spock and Amanda had built many years ago in the backyard, and sat down.

Surlek handed Spock the baby. She happened to have the same name as Spock's bonded mate, T'Pring.

"I wish I had a sister," Spock said longingly, redoing the bow in her hair.

"You can borrow her," Surlek offered, "Be a cousin or an uncle or something."

"But I want a half-human sister," he said.

Surlek shrugged,

"What can you do?"

"I am going to figure out how to get my parents to have a baby," Spock said.

"But you will have to wait," Surlek countered, "Everyone knows that babies are only born in the spring of sevens."

"I suspect that is not the case," Spock responded, "My mother is human, and humans have babies year round. I just need to do some research to find out how."

The baby started crying, and Spock gave her some vegetable juice. Then Amanda walked in.

"Is that baby T'Pring!?" she squealed. Surlek nodded.

"She is so sweet," Amanda crooned picking her up. She bounced her a bit.

"It's been so long since I've held a baby," she whispered. He voice was a combination of joy and excitement and perhaps that human emotion, regret.

Amanda whispered baby talk, and this confirmed Spock's suspicions – that regardless of what she said, his mother really wanted another baby.

She is sure lucky she has such a logical son to help her out, Spock thought proudly.

*****

"I have made progress on my research," Spock declared. He and Surlek were in the playhouse, caring for T'Pring again.

"What research?" Surlek asked.

Spock looked at him disdainfully, as if it was obvious.

"Research for Project New Sibling," he said.

Surlek looked uneasy.

"You know you are going to have to get them to, well, mate," he said finally.

"I know that," Spock replied, "The question is how."

Surlek took the baby on his lap.

"You could ask them," he suggested.

"That will not work," Spock said quickly, "As my mother is illogical and does not know she wants a baby yet."

Surlek looked confused.

"What is your plan then?"

"Well ..." Spock said a bit proudly, "I was looking up why so many babies are born in the spring, and I found a human article that says it is due to summer romance."

Spock said the word in standard.

"What is romance?" Surlek asked.

"I looked that up too," Spock replied, casting Surlek a glare, as if he expected to be appreciated for how smart he was, "The Vulcan-English dictionary said that it is a human term for a setting or mood that encourages one to engage in mating behaviours."

Surlek stared at him blankly.

"Do you not see how helpful this is?" Spock cried, "All I need to do to get them to mate is to create romance."

Spock was smiling, and Surlek gave him the sign they had agreed on to indicate this, tapping two fingers on his throat. Spock quickly stifled the smile.

"And even better," he continued, forcing monotone, "I found instructions."

He held up a PADD bearing the title, Ways to Add Romance to Your Marriage.

A/N: Writing about little Spock in the last fic was so fun I wanted to write more :) This is written for the following LJ prompt:

Little Spock is lonely. He feels that the only one who could ever truly understand him is another half-human, half-Vulcan. So, he sneakily tries to get his parents to make him a sibling.
