Hailee Steinfeld revealed her baby girl’s name in a heartfelt letter posted to her Substack, Beau Society, on Friday, June 19.
The 29-year-old actress and singer addressed this message directly to her baby, Harper Haize Allen, the first child she shares with husband Josh Allen, the NFL quarterback she married in Santa Barbara last May.
The couple announced they were expecting in December and welcomed Harper in April.
The letter was tender and unhurried, capturing with striking clarity the peculiar disorientation of new parenthood.
“You’ve only been here a short time now, and somehow you feel like you’ve always been ours,” Steinfeld wrote.
“There are times (like right now, when you sleep so soundly on my chest), I still look at you and wonder how real you are. These last few months have been beautiful and exhausting. Sacred and so special. The longest days and the shortest season all at once.”
She reflected on how the transformation of becoming a mother doesn’t come easily.
“It’s not always in the big moments,” she wrote.
“Sometimes I realize that I no longer measure time in months or years, but in ounces, in missed and miraculously taken naps, in diaper changes, and in the quiet triumph of a successful transfer from my arms to your crib.”
She also wrote about the bittersweet awareness of time already passing.
“Everyone tells me not to blink. Now I understand why. Because already, I miss versions of you that still seem like they were yesterday.”
And looking ahead: “I might cry thinking about your little toes getting bigger, but I know that one day your big girl feet will carry you through this big world.”
The letter ended with the sentence that perhaps said most simply: “My heart now lives somehow outside of my body and it always will.” »
