Doctors say they have no idea how an eight-month-old baby came to weighs the same as a child of four.
Chahat Kumar was born an average weight, but as the months went on she ballooned to become morbidly obese, now weighing almost three stone.
Her parents in Punjab, India, have taken her to the doctor to try to help her, but medical staff have found it hard to take blood samples because of the levels of fat and because her skin is harder than that of other children.
Photographs taken on March 22 show her at home, playing and with family members.
Her parents don’t know what has caused her daughter’s insatiable appetite, saying she eats as if she were much older.
‘When Chahat was born, she was completely normal,’ her dad Suraj Kumar, 23, said.
‘Then, slowly we saw that her weight was shooting up.
‘Her weight is increasing day by day.’
Her mum Reena, 21, said: ‘Before Chahat, we had a son who died, and then Chahat was born. I am concerned about her health.’
‘She doesn’t eat like a normal kid. She keeps eating all the time. If we don’t give her anything to eat, she starts crying.
‘She cries to go out but her weight is too much and we are not able to pick her up. So we only take her to nearby places.’
Her condition is affecting her as it is making it more difficult for her to eat and sleep.
‘It’s not our fault. God gave this condition to her,’ Suraj said. ‘It’s not in our hands. I feel bad when some people laugh at her for being fat.’
The family doctor Vasudev Sharma said they had tried ‘many times’ to do a blood test but: ‘Her skin is so hard that we can’t ever diagnose her condition.’
He recommended the family see a pediatric specialist in Amritsar but so far they have been unable to afford to go.
