When Kayla abandoned her baby, I gave up everything to raise him as my own. Fifteen years of scraped knees, birthdays, and bedtime stories later, she waltzed back into his life with a car and stole him away. Five years later, a knock at my door turned everything upside-down.
I hadn’t seen my little sister, Kayla, for months, but now she was on my doorstep with a bundle in her arms — a baby boy, maybe six months old, half-asleep and fussing.

Her usually perfect eyeliner was smudged down her cheeks, and that designer perfume she always wore had faded to something stale and sad.
“Please look after him, Mae, just for a couple of weeks while I figure things out,” she mumbled, thrusting a diaper bag into my free hand.
“What?” My fingers clenched reflexively around the bag strap. “Kayla, what happened? When did you—”

“It’s complicated.” She adjusted the baby as though her arms might break beneath his weight. “But I’ve got some opportunities lined up. Good ones. I just need breathing room, time to settle in. Two weeks, tops, Mae. Please.”
That was Kayla-speak for “I’m in trouble again.” Her eyes, so much like mine but always wilder, darted to her car.

“Two weeks,” I repeated firmly.
“You’re a lifesaver, sis.” She flashed me a relieved smile as she handed the baby over. “I’ll call tomorrow.”
But weeks blurred into months, and Kayla vanished like smoke.

The only communication was a text every few weeks: “Need more time” or “Can’t talk now.”
Then nothing at all.
Until three months after she left, when an envelope arrived in the mail. Inside, was the baby’s birth certificate, and a nasty surprise.

The certificate was blank where a name should be. So, he was official, but nameless. It listed Kayla as the mother and no father at all.
I thought of my grandfather, Liam, the only stable male figure in Kayla’s and my chaotic childhood. He had been kind, steady, patient.
Then I looked at the little boy playing on the floor with his toys.

“Liam it is,” I decided.
That night became the first of many landmarks: first steps across my living room, first words, first day of kindergarten.
I became his everything — rocking him through fevers, staying sleepless through teething nights, and laughing as we built towers and chunky wooden puzzles, and stuck our tongues out at each other.
