Dang! I've been into K/S for years, but this kink meme is leaning me more and more towards S/U and K/M. This prompt made me melt ;) I'm not sure if this is exactly what you had in mind though...

T'Amanda was the most beautiful baby he had ever laid eyes on, but Spock was fully ready to admit his feelings towards the 12 week old infant in his arms were biased and his opinion was far from logical.

She had light caramel colored skin, dark eyebrows and ears that came to a slight point. Her large brown eyes seemed to take in everything around her, and they often made him remember a phrase his elder self from the future had said upon seeing her for the first time. The ambassador had lifted one eyebrow and noted,"She looks as though she knows all the secrets of the universe, does she not?"

Those eyes were regarding her now, so seriously. He wondered what kind of person he seemed to this small being. The humans around them often made strange expressions and noises for her amusement, and the first time he had seen T'Amanda smile at their antics Spock had wondered if the small amount of Vulcan blood the baby possessed would show itself later. He also wondered if he would seem cold and emotionless to her, the way his own father often had in comparison to his more emotional human mother.

It had been only 87 days since his daughter's birth, but Spock found himself already feeling concern about who she would possibly become and the ways she might forever be apart from him. For the first time, his father's attempts to control his education and experiences when he was younger seemed logical. He could not conceive of leaving her future to the emotional whims her human impulses might direct her to, yet he had no doubt her strength of will would be similar to her mother's and leave him little choice.

Her dark eyes still followed him warily. He lifted a finger towards her and felt her fist, small but strong, enfold it. Through the touch, he sensed her thoughts, as primitive as they still were. They telepathic link between them consisted of images and emotions rather than actual words.

*warm touch, comfort, dark eyes, familiar mind, want attention, desire to be held*

Spock gently picked his infant daughter up and carefully placed his hand to the side of her forehead. *My mind to your mind. My thoughts to your thoughts.*

As gently as he could, he sent answering responses to her fragile mind. *My daughter, you are of great importance to my life. Your mother and I are very pleased with your presence. You are beyond all our expectations*

*I will not ask you to be an outsider among my people. I will not expect you to conform to the norms of either species. You may simply be... yourself."

He felt her consciousness still and fade into sleep. He carried T'Amanda back to the bed to rest beside her mother. Nyota claimed that human infants needed this closeness in order to develop a secure attachment, but Spock had consistently pointed out the illogic of this with the argument that no Vulcan child every slept so close to their parent. It suddenly seemed a ridiculous and illogical thing to have conflict over, as his daughter wiggled closer to rest closer against her mother's breast and let out a soft sigh. Who was he to attempt to determine her needs when she could express them to him so clearly.

It seemed to merit a human response from him as well, and he repeated the words he had only ever spoken before to his child's mother.

"I love you."

Spock then curled into bed on the other side of T'Amanda, her mother a warm presence on the opposite side of her and for the first time since her conception, allowed himself to relax and bask in the simple human contact of the two females that his family now consisted of. It was enough.
