Spock/Childhood

Spock was born on January 6, 2230 in the city of Shi'Kahr on the planet . His mother was Amanda Grayson, a Human school teacher, and his father, Sarek, was a Vulcan scientist and diplomat. (; ; )
After his half-brother Sybok's mother died, Spock and Sybok were raised as brothers. ()
Spock's mixed parentage caused difficulties throughout his early life. His own father, despite having married a Human woman, was ambivalent about his son's half-Human nature at his birth. For her part, Amanda watched Spock's stiff-lipped anguish caused by torment at the hands of other Vulcan children who repeatedly attacked and teased him to provoke emotional responses, knowing that his "Human half" was suffering. (; ; ; ) Spock himself indicated that emotions confused him. () 
When Spock was a child, he seemed to have fewer filters, and everything reached him. He also suffered from L'tak Terai, the Vulcan equivalent of dyslexia which he had inherited from his mother. Amanda intervened early on to ensure that her son was able to work past his learning difficulties. As part of her efforts to assist him, Amanda read Alice's Adventures in Wonderland and Alice Through the Looking Glass to him. (; )
As a child, Spock was betrothed to T'Pring in accordance with traditional Vulcan marriage procedure. ()
In 2237, at the age of seven, Spock decided prematurely, and without parental knowledge or approval, to undertake the kahs-wan in the Vulcan wilderness in an attempt to prove himself. His pet sehlat, I-Chaya, tagged along against his master's wishes and defended Spock from a le-matya. The intervention of an older cousin saved Spock from the le-matya but I-Chaya was left badly wounded. Faced with the choice of a painfully extended life or a peaceful release for I-Chaya, Spock logically opted for the latter. That decision marked his choice of following Surak's philosophies of logic and emotional control. In 2269, the accidental creation of an alternate timeline created a universe in which Spock was killed in his childhood. Using the Guardian of Forever, Spock returned to the Vulcan of his youth and assumed the role of Selek, the nearly-forgotten cousin who saved his life during the kahs-wan ordeal. ()
Spock often disappeared into the mountains for days as a boy, refusing to tell his father where he had gone or what he had been doing. He ignored Sarek's forbiddance of his trips, and silently endured punishment. ()
After the apparent death of two Human scientists on Doctari Alpha, Sarek considered it his and Amanda's responsibility to take in the scientists' daughter, Michael Burnham. () Upon being introduced to his new foster sister and being told he was to teach her the ways of Vulcan, Spock was not very welcoming to her. Upon seeing Michael enter the house, he withdrew into his room and drew an image of a dragon-like monster with his computer tablet. He flung the image at her and it screamed at her, after which he shut his door to her. ()
Later, however, Spock became what Michael described as her "little shadow." After logic extremists bombed a Vulcan Learning Center targeting Michael, she resolved to run away from home, believing if the logic extremists could not get to her, they would target Spock. Spock confronted her as she tried to leave and tried to convince her to stay. Michael deliberately insulted Spock's parentage to drive him away from her, leaving Spock distraught as she fled. Michael was subsequently found after Spock told his parents where to find her, claiming this information was given to him in a vision from a being he called "the Red Angel." His parents assumed the Angel was a figment of his imagination and that Spock had used logic to pinpoint her direction, but he never wavered from the belief that the Angel was real. Michael's insult to Spock also caused a long-lasting change: He withdrew and lost trust in other people, and his openness vanished. Burnham later reached out many times to make amends but Spock did not appear to be interested. ()
After Michael's graduation from the Vulcan Science Academy, Sarek was forced to choose between Michael and Spock as to who should join the Vulcan Expeditionary Group. He chose Spock over Michael but he came to regret this decision as Spock chose to join Starfleet instead. Sarek had given Spock his first lessons in computers and set him on a path of science. Therefore, Spock's preference to pursue a scientific career in Starfleet caused a rift between him and his father that kept them from speaking to each other for eighteen years. (; )
