An employee at a Jersey City daycare has been charged with breaking the leg of a 4-month-old boy she was so supposed to be caring for.

Nineteen-year-old Heather McDonald was arrested Wednesday. Her lawyer, Daniel Welch, told The Jersey Journal that she expects to be released from jail on bail.

Authorities say she broke the baby's left tibia with her hand on Aug. 6. The child's mother took him to a hospital later last week after noticing discomfort.

Hudson County First Assistant Prosecutor Debra Simon says the baby is in a cast and recovering.

McDonald is charged with aggravated assault, child abuse and endangerment for failing to seek treatment for the child.
