A mother in India has given birth to a 6.8kg baby girl, believed to be the heaviest female infant born. The child weighs the same as the average six-month-old and is reportedly twice the size of the average baby.The baby, who is unnamed, was delivered by caesarean section to her 19-year-old mother, Nandini.Doctors believe her weight overtakes that of the current record holder Carisa Rusack who weighed 6.5kg when born in Massachusetts in 2014.Venkatesh Raju, a health officer, said: "In my 25 years of experience, I have never seen such a big baby. She is a miracle. I believe she is not only the heaviest baby born in India but the heaviest baby girl born in the world."Doctors and family were surprised by her size because the pregnancy went smoothly. Nandini weighs 92kg and is 1.8m tall. She had no idea she was going to give birth to such a large baby.Medics are monitoring the child in an intensive care unit to check her development before discharging her in a few days.Poornima Manu, the gynaecologist who delivered the baby, said: "She came as a big surprise for all of us. The surgery took place for nearly half an hour and it was free of any risk. She is really big and beautiful."She does not have any health issues such as irregular sugar levels or thyroid and is breathing well. We were initially concerned about her sugar levels but that is normal."The mother made regular visits for check-ups at the hospital and did not show signs of gestational diabetes or thyroid disorders."Despite being "big and beautiful", the unnamed baby is far off the current Guinness Record holder for heaviest birth. This is held by an Italian baby boy, born without any health complications at 10.2kgin September 1955. ..
