Her mom, Nadine Sobers, spoke out exclusively to Eyewitness News, saying her daughter underwent surgery Saturday and is able to communicate by gestures.
"This is hard," she said. "I've given birth, I can do that. This is the hardest thing I've done in my life."
On Monday, she spoke to supporters at the rally.
"We can't just keep saying it can't happen to me, because it can," she said. "I never though that my daughter going to school on Friday morning would end up with my daughter being in the hospital Monday afternoon, and I'm still fearful. And I know I have to be positive, but that fear is still there, the possibility that it could go left instead of it keep going steady. And I have to be strong for my daughter, and sometimes all I really want to do is curl up in a ball and scream. Because how do I help her when I'm so scared that I might lose her?"
Neighbors said the park was filled with families and children when gunfire erupted, sending everyone scrambling.
Kyla is recovering at Brooklyn Methodist, and doctors were able to remove the bullet from her head that thankfully did not hit her brain.
She has to be intubated to keep the swelling down.
