Authorities say Bouchard had a sexual relationship with a second 14-year-old boy that began in November 2010.
Clinton police arrested Bouchard in July on the same charges involving the teen boy she was hired to baby sit. Her mother, Kimmy Bouchard, was also charged in that case with providing alcohol and marijuana to her daughter and the boy.
Loni Bouchard declined to comment while leaving court Monday.
She's due back in court Oct. 3.
