According to her mother Ebony, Aniya waited until she went to sleep then boiled water and filled a cup with it.
She poured it on Jamoneisha’s head, neck, face and chest.
She sat up suddenly, screaming and crying, and was taken to hospital.
‘Her friends wanted to play the hot water challenge and that’s what happened,’ Ebony said on social media, sharing a photograph of her little girl screaming in agony as doctors tried to treat her burns.
Jamoneisha remains in the intensive care unit at Harlem Hospital Center.
She told New York Daily News her daughter was retaliating after Jamoneisha threw cold water on her earlier in the day.
‘They always prank each other. My daughter was sleeping and Jamoni poured cold water on Aniya.
‘My daughter was like, “OK, if you’re gonna do a prank on me, I’m gonna prank you back.”
‘But my daughter — I don’t know what she was thinking — boiled hot water and poured it on Jamoni’s face,’ she said.
After learning how seriously she’d hurt her friend, she stabbed herself with a knife.
Her mother condemned her behavior but said: ‘What she did was really wrong, but it’s too much right now.
