Maybe this IS her way of grieving, honoring the Dad she loved. It may make her feel close to him by carrying on what he loved.
At 8 years old ... I doubt it. All the audience wants is entertainment. That's not consultation. Performing is not grieving. She's being raised like other precocious kids ... and the long term of it isn't good ... eventually she will have issues. It's too bad a parent doesn't parent a child anymore ... an 8 year old lacks wisdom that a parent should have ... . Too many child actors/actresses have MAJOR problems ... from taking this route.
