New mom Hailee Steinfeld is "simply obsessed."

The "Sinners" actress, 29, shared vignettes from her first Mother's Day as a mom to her and Buffalo Bills quarterback Josh Allen's baby girl.

"A day late but simply obsessed with this 💗," she captioned the Instagram post on May 11.

Among the photos were one in which her baby was clutching her left index finger, a collection of Mother's Day cards, a pancake breakfast, a "happy Mother's Day" cake, and her baby's onesie-covered feet with apple designs.

The Oscar-nominated actress, who revealed her pregnancy in December, has kept most details of her family life private. She has shared milestones, including her engagement to Allen and the birth of their daughter on April 2, which she announced in her Beau Society newsletter.
