All the children are said to be healthy, but have been kept under the observation of doctors as they are underweight as compared to normal babies, said Dr. K.R. Tekam, a paediatric at the hospital.
Dr. Tekam said that the infants have been admitted in the Intensive Care Unit as they are underweight between 1-1.5 kg.
The doctor said the woman had conceived five children and the delivery was premature as it took place in the seventh month.
The children are, however, healthy otherwise, he added.
The mother, Manita, hailing from a village falling under Lakhanpur Block, was admitted to the Civil Hospital on March 31 by her husband Umesh Kumar.
Manita's kin said a sonography test done before the delivery had detected more than two children, but five were far from their imagination.
It was Manita's second delivery, said her kin, adding that two-three years back she had given birth to a child, who died shortly.
