(NEWSER) – More than two months after she was declared brain-dead, Jahi McMath is doing "much better," in the words of mom Nailah Winkfield. They're her first public comments since moving Jahi from Children's Hospital Oakland to an undisclosed location on Jan. 5, and come via a letter to supporters posted to Facebook, the San Jose Mercury News reports. "Despite what people say about my daughter being dead and how I must be ignorant not to get that, I can tell you that she is much better physically since she has left Children's Hospital and I see changes that give me hope," Winkfield writes. "Thank you for all the love, support, and prayers you give Jahi every day ... I don't think I or Jahi would be here today without you."
