"This is a miracle," said MM Kureshi, the doctor who attended to the child.
The incident - which took place on December 30 - was captured on CCTVs in the building's parking lot, where Mahi Desai landed. NDTV is not using the footage, which is very disturbing.
Mahi was playing on the roof in the afternoon, supervised by her grandparents, when she accidentally fell over the side of a low wall and plunged four floors. The CCTV footage showed the child drop on the concrete floor. A neighbour can be seen on camera rushing to pick her up.
What saved Mahi was a plastic awning over a part of the parking area. Although the plastic ripped, it helped break her fall.
"A fall over 50 feet damages tissues and bones. Mahi just suffered a tiny fracture in her buttocks," said Dr Kureshi. The child is in a local hospital, where she is under observation.
"I consider this a second birth for my daughter. She is my only child. It is a miracle," said her father Hemant Desai.
