Judge Thomas told Hutton that she "must be regarded as a real danger to any child with whom you may live, or in any way have care of in the future".
He said the manslaughter of Hamzah involved "failing to provide him with anything like adequate nourishment over a long period of time - in short you starved him to death".
He said the child cruelty charges relate to a period of nearly three years when she forced her children "to live in quite appalling conditions of squalor which understandably shocked even the most seasoned police officers" who visited her home.
Following the conviction of Amanda Hutton, questions are raised over two little boys killed by those who were supposed to care for them.
A mother who starved her son to death threatened to kill her other children, a judge who sentenced her to 15 years in prison heard.
For two years the mummified body of four-year-old Hamzah Khan lay hidden in his mother's squalid house.
