Overview
- Steinfeld announced the baby’s full name, Harper Haize Allen, in a letter posted to her Beau Society newsletter on Friday, June 19.
- The letter addresses her daughter directly and describes the emotional, small moments of early parenthood such as naps, diaper changes and late‑night feeds.
- Josh Allen amplified the announcement by reposting Steinfeld’s Substack entry to his Instagram Stories and reacting with heart and tear emojis.
- The couple welcomed their first child in April 2026 and were married in Santa Barbara on May 31, 2025, and they have since shared only selective images and controlled updates.
- Coverage noted the use of a direct-to-fan channel for the reveal and that Steinfeld plans to spend the summer intentionally present with the infant, underscoring their choice to balance privacy with public interest.
