Police said Sonya Reilly, 45, of Stonehouse Road in Trumbull was released on a promise to appear in court Sept. 16.
A person reportedly called police and said Reilly had left more than one child in her car while she was in a store, and then returned to her car and drove to another store. She left the children in the car again unsupervised, according to a police report.
Police responded and stayed with the children until Reilly returned to the car. The Department of Children and Families was notified.
