"Daddy, Daddy, wake up it's Christmas" Skylar begged, tugging on Spock's arm as he laid face down in his bed.
"What time is it?"
"The time is six hundred hours. Alpha shift will begin in approximately three hours, Commander." The computer announced, it's mechanized voice filling the room. Spock forced himself to rise from his bed. He had finally gotten Jim to leave his quarters only three hours ago, and he knew that if Spock himself hadn't gotten enough rest, his human companion had barely even begun to rest. Skylar had climbed onto his bed in one of his leisure uniform shirts that she was using as a nightgown. Spock had always allowed himself to appreciate how adorably innocent his daughter looked in the shirt that fell all the way to her ankles and nearly hung off of her tiny shoulders.
"Skylar, perhaps you should go rise Aunt Nyota and your Papa." Spock recommended as the 3 year old began to jump around on his bed, attempting to take his quilt at the same time. She hopped off the bed and made for the door then stopped. "I have to go potty, Daddy." She announced, pulling on his hand.
"… Very well." Spock said. He had planned to rest perhaps for a few more minutes after she left, but that plan was obviously unacceptable. The vulcan stood shirtless and took his daughter's hand, leading her to the bathroom in his quarters and pushing down her big-girl undies before placing her on her potty. "Would you like me to leave?"
"I can do it on my own!" She squealed, wiggling on her seat.
"As you wish." Spock said, turning and exiting the bathroom, dressing himself while he waited. Once he was dressed and Skylar had emerged form the bathroom, he took her hand and the two walked to the Captain's quarters, rousing Uhura along the way.
When the three arrived at Kirk's quarters, Kirk opened the door, smiling eagerly. Evidently, Spock thought, Kirk was as excited about this as Skylar was. "Presents! Santa came!" the toddler squealed, attempting to pull her hand from Spock's grip in order to obtain the desired objects.
"Not so fast, Sky." Nyota poke, kneeling beside the girl. "Let me tie your hair back before you get tape in it." She said, tying the girl's fine black hair into pigtails that exposed her pointed ears.
Spock did not understand why Kirk enjoyed soiling their daughter so. She got a mountain of presents on her birthday just a month ago, and yet there was another mountain of presents next to the coffee table that supported a two foot potted evergreen. Though he did not understand the gifts, he understood Jim's desire to give their daughter what he could not have as a child, and thus obliged in the gifts and traditional holiday celebrations that Nyota and Jim reveled in.
When the four were inside Jim's quarters with the door shut, Skylar went to work tearing the paper off her new toys and throwing it haphazardly. As skylar amused herself with the gifts, Spock produced two gifts from beneath Jim's bed which he had hidden there without the captains knowing. He handed one each to his adult companions.
"I researched the holiday and found that gifts were exchanged for adults as well. Therefore I thought it apt to obtain gifts for you as well."
"Aw, I didn't get anything for you guys." Uhura said, holding the gift in her lap.
"Spock, that is so awesome of you. I didn't think to get gifts either."
"That is quite alright. I obtained gifts for you on my own volition, expecting none in return. Please open them." he requested calmly, watching his peers. Nyota opened hers first, an oddly shaped package wrapped in green paper with silver stars on it and a red bow. From the riped paper emerged a dilapidated-looing white dog with brown spots.
"Oh my god, Spock." her eyes were tearing.
"I requested your Father's suggestion for a gift and he said that something from your childhood would be apt; a 'taste of home' he called it." Spock explained as the communication's officer clutched the plush to her chest tightly.
"I got this when I was born. He was my . Thank you Spock, this is perfect!" She cooed.
"I did not mean for you to cry, Lieutenant." Uhura laughed,
'It's alright Spock. Go ahead, Captain, open yours." She smiled, wiping her tears away.
Jim unwrapped his gift a square package in the same wrapping style. Once the boiw had been stuck atop Spock's head (with a raised eyebrow in return) and the paper discarded, Jim was left holding two old books; honest to god paper books. "William Shakespeare's Othello, the Moor of Venice and Richard III." Kirk said, flipping the pages of the plays gingerly, "Wow, Spock. This is amazing." He confirmed, in awe of the two books. An appreciation of Shakespeare has been one of the initial things that he and Spock had bonded over. Kirk stood and hugged the vulcan around his neck.
"Daddy, look!" Skylar yelped, demanding attention from the three adults that had left her unattended. She was holding up a brightly colored plush toy with three eyes and a silly mouth that were interchangeable. (It's called a Smooshie-- google it.) "I got this too!" She said excitedly, holding up a stuffed toy that was representative of a strand of DNA.
"You have more presents to open, Sky." Kirk said, pointing beneath the table to where many gifts still laid wrapped. The girl had taken to playing with the toys she had opened and ignored the rest. The toddler returned top opening gifts, picking up a large one wrapped in pink paper. She pulled out a fluffy pink and purple tutu-like skirt and a black leotard along with pink tights (to match the tutu) and black ballet slippers. This gift was from Nyota. "Papa! Papa, papa!" She said, scrambling over to Kirk, "How do I out this on?!" She asked excitedly. Kirk stood and took her behind the screen where his bed lay and helped the toddler get dressed.
Skylar would spend the rest of the day running around the ship in her new tutu.
A note on the relationships here: When Spock and Uhura were dating Spock got her pregnant unintentionally. During the pregnancy, they broke up when Uhura realized he was in love with Kirk, and therefore the parenting is shared between the three. Spock and Kirk are in a committed relationship.
