The toddler, Rehan Khakra fell on concrete and survived miraculously with only minor concussion and cuts.
The 13-year-old maid threw the baby out of balcony in an act of revenge for being scolded by Rehan's family and is currently sent to a juvenile remand home.
The girl was brought to Rehan's family by her grandmother and requested the Khakra's to employ her since she was a orphan.
"The old woman said the girl was an orphan and had nobody to look after her. She requested us for help. Though we have enough domestic help, we took pity on her and gave her a job to look after our children and play with them," said Rehan's aunt, Parveen.
She further added that the domestic help, Ruksana (name changed) was careless and would often drop things. On Sunday after the family finished their sehri in the morning, Ruksana broke a a glassware accidentally following which Tehseen (Rehan's mother) scolded her.
After Tehseen left in the morning to drop her daughter to tuition, the maid took Rehan to the balcony to play and placed him on the railing, thinking he would fall on his own. Ruksana threw the baby after ensuring no one saw her after Rehan failed to fall on his own. Assuming that he was dead, she went inside.
The incident came to light when a few neighbours spotted Rehan lying in a pool of blood.
"His eyes were rolled up and we could not feel his pulse. He had bitten his tongue... there was blood everywhere. We were scared he would choke on his own blood," said Rehan's father.
The baby was then taken to Prince Aly Khan Hospital and CT scan suggested that he had minor concussion and superficial injuries. Rehan is currently in pediatric ICU.
The maid confessed to the crime and begged that she be forgiven. A case of attempt to murder has been registered against her.
"We have found that they took the girl in to help her; she was basically hired to play with the children. In case something else comes up in the course of our investigation, things might change," said Sanjay Kadam, Police Inspector, Nagpada police station.
