"There is something broken and something missing in you," Judge Wells Ashby told her at the sentencing hearing last week.
Parents and family of some of the children who were in Neatherlin's care were in the courtroom.
Neatherlin: I 'failed' parents
"I don't know what's wrong with the defendant; I don't know what could bring a person to do what she's done to the most helpless and innocent people in our society," Les Adams, a grandfather of one of the kids, said at the sentencing hearing.
"But I hope she can understand that she damn near killed the easiest, happiest, most easygoing baby I've ever known in my life."
Neatherlin offered a tearful apology in the courtroom, according to KTVZ. She told parents she "failed" them and loved the children as if they were her own.
"Everybody makes mistakes, but not everybody takes responsibility for those mistakes," she said. "With that said, I pray that the court and the parents accept my apology, It was never my intention to put any of your children at risk of injury or harm."
