Sarah Kuiper-Boles, 29, told investigators that she shook the 6-month-old so violently, she was afraid to demonstrate using a doll because the doll’s head might come off, according to court documents.
On one occasion after she shook him, she told investigators, the baby’s eyes rolled back in his head and he vomited and went limp. She said she shook the baby because she was angry and frustrated that he wouldn’t stop crying, according to court documents.
On Wednesday, 3rd District Judge Molly Huskey sentenced Kuiper-Boles to at least four years in prison, and up to 10, for felony injury to a child.
“I have a disabled baby because of (Sarah),” the infant’s mother wrote in a prepared statement given to the Canyon County sheriff.

The child, now 11 months old, has had five surgeries since his injuries were discovered in February and might need more, his mother wrote. He has developmental delays, she said.
She urged people to look into the history of potential babysitters and ask for references. Kuiper-Boles watched the little boy during a two-month period.
Wilder police investigated Kuiper-Boles after a doctor at St. Luke’s reported the boy’s injuries on Feb. 9. The child, then 6 months old, had chronic subdural hematomas on both sides of his brain, abnormal eye movements and brain injuries consistent with lack of oxygen, the doctor reported.
“This is one of the most disturbing cases of injury to a child that I’ve ever seen,” Prosecutor Bryan Taylor said in a news release, crediting the investigative work by the Canyon County Sheriff’s Office and Wilder police.
Kuiper-Boles, who has been in the Canyon County Jail since her arrest in February, changed her plea to guilty in March.
In addition to the prison sentence, Huskey ordered Kuiper-Boles to pay a $5,000 civil penalty and pay court costs. A no-contact order bars Kuiper-Boles from having any contact with the child, his family or any minor for the next 10 years.
