As her son, Avyaan Azaad, turned one on Saturday, actor Dia Mirza penned an emotional note, recalling how the little one fought severe health conditions.

"Our Jaan, our miracle, you were born on this day one year ago with the song Imagine playing. You were three months premature at 820 grams. Thirty-six hours after birth we discovered you had necrotizing enterocolitis and had to go through life-saving surgery. You were cared for and nourished in the NICU with a stoma for 90 days and finally sent home to us with a stoma," Dia wrote, in an Instagram post.
