"The condition of the baby deteriorated last night after she was breastfed by her mother. The milk entered into her lungs following which some complications developed and she was put on ventilator support but she died," Spokesperson of the Sawai Man Singh Government Hospital here said.
The girl was operated upon on Februrary 1.
Police said the baby's 36-year-old father Bahadur Singh will be charged with murder.
The baby had underwent a reconstructive plastic surgery on February 1 at the Sawai Man Singh Government Hospital here and the doctors had said the baby was able to breathe and swallow better following the operation that went on for over five hours. But her condition turned critical following which she was put on ventilator early on Wednesday.
The accused, Bahadur Singh, worked as a trucker and after losing an arm in an accident had started working as an agricultural labourer.
Her three-year-old elder sister, who was also bitten on the back and hand, is in hospital too. The injuries on her hand have got infected.
The babies' mother has said she decided to flee her alcoholic husband of 17 years, Bhadar Singh, after he attacked both their daughters.
On the night of January 24, she said, he had come home drunk and asked her to do some work. She had said she had mehndi on her hand and asked him to wait.
Flying into a rage, Singh had allegedly first started beating her up and when their elder daughter raised an alarm, bit her on her back and hand.
Awakened by the commotion, the five-month old had started crying and Singh allegedly rushed to the baby, picked her up and bit off her nose and upper lip and swallowed them.
She said she had fled the same night with her daughters and hidden in the fields. Next morning she had filed an FIR with the help of social workers. She has been socially ostracised since while her in-laws have been pressuring her to withdraw the case.
Deepak Kalra, Chairperson, Child Rights Commission said, "It is really very sad. She developed respiratory complications last night. She was put on ventilator and we were hoping that she would come out and fight like she was fighting for the last 10 days but unfortunately she succumbed to the complications.
"As you know the surgery was five-and-half hours long. There were three surgeries that were done at one go and then she had to undergo two more surgeries. The case was complicated and unfortunately she could not go through it," she said.
