“Okay, you win. But to be fair, she smells better than most of the people on the bus.” I plant a small kiss on Viv’s head and tuck her more securely into the crook of my arm before carefully reaching for my coffee.

The cup feels strange in my hand. It’s ceramic, not a paper throwaway or the enormous stainless steel travel mug Sean fills to the brim for me each morning, assuming— not incorrectly—that it takes a hulking dose of caffeine to get me ready to tackle the day. It’s been forever since I had time to sit down with an actual mug and sip any- thing.

“You already look like a mama,” Sabrina says, watching us from across the small café table.

“The benefit of working with babies all day.”

Sabrina is quiet for a breath, and I realize my mistake. Ground rule number one: never reference my job around mothers, especially new mothers. I can practically hear her heart stutter across the table from me.

“I don’t know how you do it,” she whispers.

The sentence is a repeating chorus to my life right now. It seems to boggle my friends over and over again that I made the decision to go into pediatrics at UCSF—in the critical-care track. Without fail, I catch a flash of suspicion that maybe I’m missing an important, tender bone, some maternal brake that should prevent me from being able to routinely witness the suffering of sick kids.

I give Sabrina my usual refrain of “Someone needs to,” then add, “And I’m good at it.”

“I bet you are.”

“Now pediatric neuro? That I couldn’t do,” I say, and then pull my lips between my teeth, physically restraining myself from saying more.

Shut up, Macy. Shut your crazy babble mouth.

Sabrina offers a small nod, staring at her baby. Viv smiles up at me and kicks her legs excitedly.

“Not all the stories are sad.” I tickle her tummy. “Tiny miracles happen every day, don’t they, cutie?”

The subject change rolls out of Sabrina, loud enough to be a little jarring: “How’s wedding planning coming?”

I groan, pressing my face into the sweet baby smell of Viv’s neck.

“That good, huh?” Laughing, Sabrina reaches for her daughter, as if she’s unable to share her any longer. I can’t blame her. She’s such a warm and shapable little bundle in my arms.

“She’s perfect, honey,” I say quietly, handing her over. “Such a solid little girl.”

And, as if everything I do is somehow hardwired to my memories of them—the raucous life next door, the giant, chaotic family I never had—I am hit with nostalgia, of the last non-work-related baby I spent any real time with. It’s a memory of me as a teenager, staring down at baby Alex as she slept in her bouncy chair.

My brain leapfrogs through a hundred images: Miss Dina cooking dinner with the swaddled bundle of Alex slung against her chest. Mr. Nick holding Alex in his beefy, hairy arms, staring down at her with the tenderness of an entire village. Sixteen-year-old George trying—and failing—to change a diaper without incident on the family couch. The protective lean of Nick Jr., George, and Andreas as they stared down at their new, most beloved sibling. And then, invariably, my mind shifts to Elliot just beyond or behind, waiting quietly for his older brothers to move on to their fighting or running or mess making, leaving him to pick up Alex, read to her, give her his undivided attention.
