Hailee Steinfeld and her husband, Buffalo Bills Quarterback Josh Allen, welcomed their first child in April 2026. Hailee has more than 20 million followers on Instagram and has kept her baby girl off of social media, revealing very few details.

On June 19, 2026, Hailee Steinfeld posted an open letter to her baby girl on her Substack, Beau Society, revealing she named her Harper.

“I’m in awe of you,” the new mom wrote. “You’ve been here for only a short while now, and somehow it feels as though you’ve always been ours.”

“There are moments (like right now, as you sleep so soundly on my chest), I still look at you and wonder how you’re real. These last few months have been beautiful and exhausting. Sacred and so special. The longest days and the shortest season all at once.”

Hailee Steinfeld Wants to Savor Every Moment with Her Baby Girl

Hailee Steinfeld went on to talk about her baby girl and how everyone warned her that time would go by so quickly.

“I’ve learned that motherhood isn’t made up of grand moments as much as the tiny, precious ones. The sway of tired hips in the middle of the night, your little milk-drunk smiles, and the quiet realization, over and over again, that my heart is now somehow living outside of my body and it always will,” Hailee added.

“And even though I know I am meant to guide you through this life, Harper Haize Allen, the truth is that already, you have taught me far more than I could ever teach you. One day you’ll read this and know that to be true, my sweet girl.”

Marriage and motherhood look great on Hailee Steinfeld. What a lucky family.
