"Ah! AHHHH! Guh…" Spock drowsily looked down at the infant that was using his knee as a support to stand.
"What?" He offered, knowing full well the little girl would not answer comprehensively, and therefore his response to his child was illogical. However, his exhaustion overpowered his logic.
"Daaaaaa! Uhda! Uhyayayaya." Spock quirked an eyebrow and lifted the girl, seating her in his lap in her pink onesie decorated with the Starfleet insignia. The pointy-eared girl squirmed in his lap and reached forward, laying on his knee, looking at the floor and wiggling as she reached toward it. Spock understood and bent down to sit her between her legs, slouching back in the Captain's chair.
Days before, when Spock agreed to take gamma shift, he had not realized that circumstances would lead to said gamma shift being precedented by sixty hours without sleep at all. True, his vulcan physiology allowed him to go with less sleep than humans, but he still had his limits. In addition to his lack of sleep, Spock had also not expected to be accompanied by his daughter.
With the support of his leg the 11-month-old bounced up and down excitedly for reasons unknown. She squealed and apparently found something very exciting. Her ability to stand, perhaps, Spock thought. "Uh Uh!" the infant commanded, which he had come to recognize as the baby's demand to be held. He did not understand the girl's logic after being sat down just minutes before, but recalled what he had been told just after the baby's birth: "She's a baby, Spock, she needs love, not logic," and he picked her up nonetheless.
He stood her in his lap, facing him and she propped herself up with one hand against his chest. The baby was of no doubt Vulcan descent. If not for her fine dark hair, pointed ears, and chocolate eyes, her unusual strength paired with her aptitude for problem solving and learning made that obvious. "Ahhh…" she sighed, letting her small body lay against Spock's chest with her head laying on his shoulder. Spock reciprocated and hugged the infant gently, but as tightly as he could while not harming her. He buried his face in her tiny arm and closed his eyes, letting his usually controlled emotion, his love, flow into her.
