A US woman in the state of Iowa has given birth to a giant baby boy weighing 6.2kg - without the aid of surgery.
Asher Stewardson was born on Thursday at Mercy Medical Center in Des Moines, measuring 59.7cm long.
Fifteen months ago, his brother, Judah, arrived weighing 5.4kg at birth.
Mercy officials say only a tenth of 1 per cent of all newborns weigh more than 5kg at birth.
The boys' mother, Kendall Stewardson, endured six hours of labour without an epidural injection.
She says she and her husband, Joshua, wanted to avoid caesarean delivery.
