Prosecutors said Kraft and her husband, Paul Kraft, 32, sexually abused their four sons and one daughter, ages 1 to 6, in 2004.
In March, Paul Kraft received five life sentences on five rape charges and 96 additional years on 12 charges of pandering sexually oriented material involving a minor. He is ineligible for parole.
Prosecutors say Paul Kraft encountered an undercover Secret Service agent last March in an Internet chat room called "baby and pre-teen sex."
In an online exchange, Kraft offered to rape his 3-year-old daughter live on the Internet if another person would do the same so Kraft could watch, prosecutors say. The agent contacted Hamilton County sheriff's deputies, who arrested Kraft at home.
