Without a more complete description of the facts and a chance to review the documents that have been filed, it is difficult to make a recommendation. However, it sounds like you may want to petition the court for a modification of the parenting plan and ask the court to appoint a guardian ad litem. The GAL will make a recommendation to the court on whether or not your daughters visitation with her mother is in her best interest.
File a Petition to modify the PP -- a child may never choose where she wants to live, so you will need a Guardian ad Litem appointed so that he child can express where wishes to the GAL who then reports to the court.
