Steinfeld reflected on the first moments of motherhood and shared her feelings after giving birth in her newsletter. The star of the film "Sinners" announced on her Beau Society Substack on April 2 that she had given birth, writing: "Our baby girl is here!! We feel incredibly grateful and blessed and are soaking up these first moments. Thank you so much for all the love and well wishes." "To say we are over the moon and in love with this little girl would be an understatement. I am in newborn bliss," she said. The couple has not yet revealed the baby's name. "There’s an indescribable peace that you have, that rock, that steady constant in your life. I literally thank God every day that I found my person; it’s the greatest thing in the world. Life makes sense. Everything makes sense. I feel like I’m becoming the version of myself I’ve always dreamed of being, and that has a lot to do with him," Steinfeld told Bustle in November. The couple kept their relationship out of the public eye for a long time, although rumors they were together had been circulating since 2023. They officially confirmed it a year later on Instagram. Steinfeld often supports her husband at his NFL games, and now they are enjoying the first moments of family life together.
