What to do?

What to do?

My 6 year old granddaughter moved during the summer between kindergarten and 1st grade. At the new school, she was sexually molested on two separate occasions by the 6 year old boy sitting next to her. He fondled her private parts under her clothes and she said she cried and asked him to stop but was scared and he didn't. We called the police when she told us, a report was made, she was extensively interviewed by Child Protective Services, who confirmed it happened, and who also confirmed that she had never been inappropriately touched before, and that she was too shocked and fearful too scream out. We changed her school.

Should I suggest to my daughter that she see a psychologist? She seems ok now, in a way, but in another way, she is extremely moody, not as joyful as she used to be, projects negative attitudes expressively often, and, at times, is ill behaved in a way she never was before. Is this typical?  

What do you think a good follow up treatment should be? My daughter says she doesn't want her to go soemwhere with some stranger and "sit around and talk about it." What do you think?

Thank you for your help.
