Ryan—who shares daughters James, 9, Inez, 7, and Betty, 4, and son Olin, born in 2023 with Blake Lively—also took a moment to shoutout Rob’s 2022 book A Heart That Works, which details the 47-year-old’s journey through grief. Ryan called it “an incredible piece of writing which explores the kaleidoscopic colours of emotion Henry’s passing revealed.”

Since Henry’s death, Rob has been open about the difficulties he and his wife Leah have faced, in addition to caring to for their other three sons—the youngest of whom they welcomed in December 2018.

“The things my wife and I had to learn to care for a one year old with a complex tracheotomy,” Rob recalled on Instagram in 2021. “But I wish to hell I was still doing it every day. I miss caring for him. Our son Henry.”

Henry—whose tumor was discovered shortly after his first birthday—underwent treatment to remove the tumor and received a tracheotomy due to cranial nerve damage, but he sadly passed on the morning of Rob’s birthday in 2018.
