Could a babysitter sue the parents with their child did this?

The following is only a hypothetical question.Suppose a teenage girl took on a job as babysitter for a girl 8-10 years old.Now suppose that while they were alone together,the child-for no apparent reason-walks up to the babysitter and deliberately sticks both of her fingers in the babysitters eyes.Would the babysitter have grounds to sue the parents for assault?
