It’s their first night at home as a family the first time he does it, Harry in the rocking chair with Sadie swaddled in his arms and Louis at his side. It starts as a soft hum and Louis’ heart swells at the sound. It’s a tune he’d recognize anywhere.
“Isn’t she lovely,” Harry starts. “Isn’t she wonderful, isn’t she precious, less than one minute old…”
All Louis can do is look on, listen, and hope to the powers that be that his brain has configured some sort of infallible high definition playback feature so he can watch this on a loop for the rest of his life. He can’t even see Harry’s face from where he stands beside him, but he knows by the sound of his voice the soft look he’s giving their daughter as he sings. Knows it by heart. He’s been on the receiving end of it enough times.
“I never thought through love we’d be making one as lovely as she,” Harry continues, “but isn’t she lovely, made from love…”
It’s only then that Harry finally tears his gaze away from the tiny newborn fast asleep in his arms, looking up at Louis with wide eyes and a smile that Louis is certain could end wars. His heart could, and very well may, burst from the sight.
“Isn’t she lovely, Lou?”
“The loveliest,” Louis replies. With that, he crouches down to Harry’s level and presses a kiss to his husband’s shoulder before resting his head against it. He feels Harry take a deep breath. When he speaks, it’s barely above a whisper.
“We’re dads, Lou.”
Even as he watches Sadie’s chest rise and fall, Louis almost can’t believe it. They’re dads. For as long as they’ve wanted this, nothing ever could’ve prepared him for the way he feels right now. He feels weightless and warm and in love. So, so in love. With his boy. With his girl. With this moment.
“Isn’t she pretty, truly the angels’ best,” Louis begins.
“Boy, I’m so happy,” Harry joins in, “we have been heaven blessed…"
And if that becomes Sadie’s nightly lullaby, Louis thinks, it’s only fitting.
