Chapter 24: The Specific Math
Declan
Nobody told you about the math.
People told you about the love — effusively, in greeting cards, in the knowing smiles of people who’d already done this, in the breathless way they said *just wait* like they were warning you about something wonderful that was also going to take you apart and rebuild you differently. Declan had catalogued all of this and filed it under *noted* and assumed he understood it in the abstract.
The math was something else.
The math was: one seven-pound person who needed feeding every two to three hours, which meant sleep happened in stretches of ninety minutes on a good night, which meant both of them were operating at approximately forty percent capacity, which meant the smallest things — a misplaced burp cloth, the specific angle of a swaddle, whether or not the white noise machine was on the ocean setting or the rain setting — became subjects of opinions so strong they surprised him.
Scarlett had a sleep schedule spreadsheet. He was not going to talk about the sleep schedule spreadsheet. He was going to respect the sleep schedule spreadsheet and its color-coded system of shift responsibilities and acknowledge, privately, that it was the only reason they were both still functional in week two.
He had suggested, once, that maybe they didn’t need the spreadsheet, that maybe they could just — go with it, see what Wren needed, be adaptive. Scarlett had looked at him with the expression of someone who was very tired and very fond of him and had chosen, generously, not to explain at length why that was a terrible idea. She had simply pulled up the spreadsheet and pointed at Tuesday’s 3 a.m. block, which said his name.
He had gotten up for the 3 a.m. block. He got up for every 3 a.m. block that had his name on it, and he had come to understand that this was love in its most granular form: not the sweeping feeling, not the delivery room proposal, but the 3 a.m. alarm and the getting up anyway because someone else needed the sleep and you were the one who’d said you’d do it.
But here was the thing about the math that nobody warned him about: it added up to something that kept astonishing him.
Wren was three weeks old when he understood it clearly.
It was four in the morning. His shift. Wren had finished eating and was doing the thing she did, which was not sleeping, which was looking up at him with the focused, evaluating gaze of someone conducting a performance review. He was sitting in the glider in the corner of the nursery — the room he and Scarlett had painted in two sessions, the crib he had assembled twice — and Wren was in his arms, her whole fist wrapped around his index finger, her weight approximately seven pounds three ounces of absolute authority over his entire life, and he was talking to her.
This had started by accident. He’d been running out of things to do at 4 a.m. with a baby who wouldn’t sleep, and he’d started telling her things. Not baby talk — he wasn’t capable of sustained baby talk; it felt false in his mouth the way things felt false when they weren’t quite true. He told her things like he was talking to a person. He told her about the campaign he was figuring out at work. He told her about San Francisco in winter, the specific quality of the fog, the way the bay looked from the Hayes Valley roof. He told her about her mother.
Tonight he told her: “Your mother is the most infuriating person I have ever worked with, which is how I knew. Infuriating means interesting means worth it, in my experience. Most things that are worth anything put up resistance. The good stuff pushes back.”
Wren considered this. Her grip on his finger tightened fractionally.
“She made me a spreadsheet,” he told his daughter. “I complained about it. She was right about it. This is going to be a recurring theme and I want you to have accurate expectations.”
From the doorway, Scarlett said, quietly: “Are you giving her a briefing on me.”
He turned. She was in the doorway in his sweatshirt — she’d claimed it in week one and he had not once suggested she give it back — her dark red hair loose, her face carrying the particular soft focus of someone who has been awake at all the wrong hours for three weeks.
“I’m giving her context,” he said.
“Flattering context?”
“Accurate context.”
She came into the room and sat on the floor next to the glider, leaning her head against the arm of it. She reached up and touched Wren’s foot, the small foot in its small sock, and Wren curled her toes.
“She’s not sleeping,” Scarlett observed.
“She’s thinking.”
“She’s three weeks old.”
“She’s precocious.”
Scarlett made a sound that was too tired to be a laugh and too fond to be anything else. “Let me take her.”
“You’re off shift.”
“Declan.”
“You’re off shift. Sleep. I’ve got it.”
She stayed on the floor anyway, her head against the glider’s arm, her hand on Wren’s foot. Within four minutes she was asleep, sitting up, against the side of the chair, in the way of a person who has lost negotiating power over her own body.
He looked at them — both of them — and thought: this. This is the thing they were trying to tell him. Not the love in the abstract. This specific math: Wren’s weight in his arms, Scarlett asleep against the glider at four in the morning in his sweatshirt, the white noise machine on ocean setting, the glow of the nightlight they’d disagreed about and then agreed on, the particular feeling of having fought for all of it and been given all of it and knowing he would do the fighting again without a second thought.
He was thirty-two years old. He had run a successful creative agency for four years. He had made things he was proud of and things he’d learned from and things that hadn’t worked and one or two things that had changed something about how people saw the world. None of it, taken in aggregate, was as significant as this chair in this room at four in the morning.
He would not have changed any of the parts that were hard. The parking lot fight and the months of uncertainty and the morning he’d driven home from her apartment not knowing if there was a them anymore. He would not have changed the proposal she’d needed to refuse, because if she hadn’t refused it he would not have watched her say yes in the delivery room, which was the most certain yes he had ever witnessed in his life, and he had needed to witness it to believe it fully.
Wren’s eyes were finally closing. He sat very still and let her go.
Then he carried her to the crib — the crib he had assembled correctly on the second attempt — and laid her down and pulled the light blanket over her the specific way the nurse had shown them, and Wren settled, and made a small sound, and was asleep.
He woke Scarlett gently, walked her back to bed, lay down beside her.
She was asleep again in thirty seconds.
He lay awake for a while longer, because that was who he was — he thought about things when everyone else had let them go — and he thought about Wren’s fist around his finger and Scarlett’s hand on Wren’s foot and the spreadsheet on the kitchen counter and the ring on her hand and the fact that in three or four months, when the spreadsheet became unnecessary and the sleep returned and the particular rawness of the early weeks smoothed into something more sustainable, he was going to marry this woman.
He had not made a lot of mistakes in his life that he was grateful for.
He was getting more grateful for this one every single day.
