Amy Schumer reveals son is "better" after being hospitalized with RSV

Comedian Amy Schumer revealed Sunday that her young son was hospitalized this past week with respiratory syncytial virus, also known as RSV. She described the experience as the "hardest week of my life."

Schumer, who hosted "Saturday Night Live" this weekend, wrote in an Instagram post that she was forced to miss SNL rehearsals on Thursday because her 3-year-old son was taken to the emergency room after contracting RSV.  

Schumer said she "got to be with him the whole day at the hospital," adding that now he "is home and better."
