Renu Singh suffers from a tumour on head that has swollen match the size of her skull and leaves her in unbearable pain.
The three-year-old cannot walk, sleep or sit normally because of the weight of her head.
Mother Pramila Singh, 30, who works as adomestic help is inconsolable with her daughter's plight.
She says: "I am helpless. I watch her cry all the time and I know she is slowly advancing towards death.
"I do not know how long she will survive with that painful tumour in head."
Mrs Singh and her husband Kumar, 32, from a tiny village in Uttar Pradesh in northern India, were unaware of the condition Renu - their eighth daughter - had been suffering from.
They took her to several local doctors but were each time told to consult a specialist in advance hospitals.
But due to their very low income they were unable to continue with any treatment.
Mrs Singh said: "She was born via normal delivery just like my other children. Because none had any complication, we never felt the need for sonography during the pregnancy.
"She was a normal child but as she grew, we noticed a lump growing in the middle of her head. At first we thought it was just a boil and would go but it only grew bigger with time.
"She would cry if I touch it or lie her down for sleep. Alarmed by her unknown condition we started taking her to doctors and were finally told it is a tumour and she can die if not operated soon."
Mr Singh said: "Doctors suggested us to take her to better surgeons but we could not as we do not have the means or money to take her to a bigger hospital or foot the bills of her treatment.
"We have so many mouths to feed from the paltry income, thinking about her treatment is beyond our capacity."
The parents are now hoping to get either medical help or financial aid from the authorities that could help their daughter get a life-saving surgery.
Mrs Singh added: "She cannot go to school nor can she spend her childhood like other children. My only hope is now to get help either from authorities or a Good Samaritan who can give my daughter the gift of life."
