Ms Lizar was sentenced on charges stemming from the death of her baby boy after she pleaded guilty November 2 to one count of child endangerment.
Judge Patrick Robb ordered Ms. Lizar to serve seven years in prison. The judge ordered this sentence to be served consecutively to the sentences forthcoming on other felony convictions.
Officials say there are several cases in which Ms. Lizar faces prison time for parole violations.
Judge Robb told the defendant that while she might know that methamphetamine made it impossible for her to provide a safe and secure home for her child, she continued to take the drug, and hang out with other people who took it.
Court documents assert that Lizar used methamphetamine while caring for her child and left him with others who had also taken the drug. One of them, Roy Miller, is charged with child abuse resulting in death for allegedly shaking young Carter Lizar violently. Investigators say that caused massive brain trauma that killed the infant.
Mr Miller is scheduled for a trial in April.
