White said she wanted a discharge because after her son, Caden, was born Dec. 10, she grew concerned that she may be called to leave him for 18 months if her unit deployed to Iraq.
"It's not that I have a problem with the military," she said. "If it was me alone, I'd buck up and say this is something I have to do. But he (Caden) changes everything."
The Army also never explained the denial, said White, who works part time as a waitress at Chili's Bar and Grill in Evansville.
Capt. Annmarie Daneker, the readiness command spokeswoman, said the military does not acknowledge pregnancy as a hardship or cause, in itself, for discharge.
Hardship discharges are based on "nontemporary situations," she said.
