Actor and singer Hailee Steinfeld has revealed the name of her daughter with Josh Allen while opening up about how motherhood has transformed her life. In the latest edition of her Beau Society newsletter published on Friday, June 19, Steinfeld shared a letter addressed to her daughter, revealing for the first time that the couple's baby girl is named Harper Haize Allen.The revelation came as Steinfeld reflected on questions from readers about motherhood and what her daughter has taught her since arriving earlier this year.Addressing her daughter directly, Steinfeld 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.”The actress described the early months of parenting as “beautiful and exhausting,” adding that they have been “sacred and so special.”Steinfeld also shared how becoming a mother has changed the way she sees herself. “Each day with you, I meet a different version of myself. A softer version. A stronger version. A more patient and present version. A version that loves everything and everyone - including myself - more deeply than she ever knew possible,” she wrote.Reflecting on life with Allen and their newborn daughter, Steinfeld said the couple often find themselves amazed by their good fortune. “Your daddy and I look at you often and ask each other the same question: How did we get so lucky to have you?” she wrote.The actress said motherhood is not defined by major milestones but by everyday moments, including late-night feedings, missed naps and small victories. “I’ve learned that motherhood isn’t made up of grand moments as much as the tiny, precious ones,” she wrote.In one of the letter’s most personal passages, Steinfeld credited her daughter with teaching her lessons she never expected. “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,” she wrote.Steinfeld first announced the birth of her daughter on April 2, telling subscribers to her newsletter that she and Allen were “feeling incredibly grateful and blessed” as they enjoyed their first weeks as parents.
