The 21-year-old reservist gave birth on Sunday at the post hospital at Fort Bragg, Col. Billy Buckner, public affairs officer for the 18th Airborne Corps, said Wednesday.
Post officials said they do not know whether the baby was a boy or a girl, but the Baltimore Sun said it was a boy, citing an unnamed military source.
England's father, Kenneth England, said the family would not release information about the birth.
England became a focal point of the scandal over the abuse of prisoners in Iraq after the release of with nude prisoners stacked in a pyramid, pointing and flashing a thumb's up, and holding a detainee on a dog leash.
Attorneys say the child's father is Spc. Charles Graner Jr., England's ex-boyfriend, who is also shown in the prison photographs, including one with a dead body packed in ice in a body bag.
England and Graner are among seven members of the 372nd Military Police Company charged in connection with abuse that occurred late last year at Abu Ghraib prison west of Baghdad.
England faces court-martial in January on charges of abusing detainees and committing indecent acts. She faces a prison sentence of up to 38 years, a dishonorable discharge and forfeiture of all pay and allowances if convicted.
