Rachel Hollis is honoring her young daughter.

The Girl, Wash Your Face author celebrated daughter Noah's sixth birthday on Tuesday with a social media tribute. "Our wildflower turns 6 today 🌻," she wrote, alongside a photograph of Noah standing outside and holding up a pair of heart-shaped sunglasses.

It marked the girl's first birthday since the death of her father, former Disney executive Dave Hollis, who died on Feb 11. In the comments section of the birthday post, a number of people said that in honor of the occasion, they would be reading his children's book Here's to Your Dreams!, which was inspired by his "teatime" series with his daughter.

"When we started doing Tea Time a few years back, the idea was simple. Could I take some of the things that I was reaching for in personal development - to unlearn a bunch of stuff that had me in my own way - and teach it to her in simple terms so that she might stay out of her way as she grew up?" he explained last year. "With this book, I hope some of the capital-T truths embed in those that read it so that when the messages of the world come, they're fortified with unflinching belief in themselves."

The birthday photo marked Rachel's first new Instagram post since Feb. 14, when she shared a statement about her ex-husband's death on what would have been his 48th birthday. "We are devastated," she wrote. "I have no words and my heart is too broken to find them."

"Please wrap the kids up in prayers as we try and navigate through the unthinkable," she added.

Rachel and Dave, who were married for 16 years before they announced their split in June 2020, share four children together: sons Jackson, Sawyer and Ford, as well as their daughter Noah.
