“As a mother, you dream of a future full of smiles, first steps, and bedtime lullabies. But this week, my family has been living a nightmare,” she wrote. “Our beloved baby boy has been diagnosed with a rare and serious heart condition.”

She continued with raw honesty, sharing how what began as a routine doctor’s visit for her son, just five months old, turned into a series of urgent hospitalizations, endless tests, and a devastating diagnosis. Although she did not specify the exact name of the condition, Leavitt described it as “life-threatening and complex.”

The post was accompanied by a tender black-and-white photograph of Leavitt cradling her son in a hospital bed, his tiny hand wrapped around her finger. The image alone sparked tens of thousands of reactions across all platforms, with fans expressing both heartbreak and solidarity.
