Jack Schlossberg is sharing an optimistic message on what would have been sister Tatiana’s 36th birthday months after her death.
“Hey everybody, it’s May,” Schlossberg, 33, said in an Instagram video on Tuesday, May 5. “It’s the month of May. I want to talk a little bit about the month of May because it’s a special month. It’s the month when things surprise you. When nature says, ‘It’s all gonna be OK.’”
He continued, “We go through winter, we see little buds on the trees and we think they might be dying or dead. And then May comes around and they surprise us with a little bit of green and a little bit of life. Our hydrangeas are blooming. Our flowers are pushing up out of the ground.”
Schlossberg shared that May differs from the month of April because you “expect the tulips” and “other flowers” then.

“But in May, May hits you like a bus with a little bit of something I like to call surprise and delight,” he said. “And that’s the month of May. A lot of people say September is the best month to be in New York City. I say it’s the month of May.”
Schlossberg captioned the video, “Thoughts …. It’s gonna be OK !!”
Jack’s sister Tatiana died in December 2025 after battling acute myeloid leukemia. She was 35. (Caroline Kennedy and Ed Schlossberg are also the parents of daughter Rose.)
“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the JFK Library Foundation shared in an Instagram statement at the time, signed by Tatiana’s husband, George Moran, their two children, Edwin, 3, and Josephine, 23 months, her parents, siblings and sister-in-law Rory Schlossberg.
Jack Schlossberg Shares the Last Thing Sister Tatiana Told Him Before She Died
Tatiana previously revealed in a November 2025 New Yorker essay that she was given a year to live after her diagnosis. Tatiana shared that she learned she had “a rare mutation called Inversion 3” after her doctor noticed an imbalance in her white blood cell count following the birth of her second child. Initially, Tatiana was told she would need to undergo months of chemotherapy and receive a bone marrow transplant.
“I did not — could not — believe that they were talking about me. I had swum a mile in the pool the day before, nine months pregnant. I wasn’t sick. I didn’t feel sick. I was actually one of the healthiest people I knew,” she wrote. “I had a son whom I loved more than anything and a newborn I needed to take care of.”
Following the arrival of her daughter, Tatiana underwent a bone marrow transplant at Memorial Sloan Kettering and received chemotherapy treatments at home. After joining a clinical trial of CAR-T-cell therapy — a type of immunotherapy to fight certain blood cancers — in January 2025, she learned of her life expectancy.
“My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me,” she recalled. “My son might have a few memories, but he’ll probably start confusing them with pictures he sees or stories he hears. I didn’t ever really get to take care of my daughter — I couldn’t change her diaper or give her a bath or feed her, all because of the risk of infection after my transplants. I was gone for almost half of her first year of life. I don’t know who, really, she thinks I am, and whether she will feel or remember, when I am gone, that I am her mother.”
