Birth grandparents' inappropriate comments

I'm also wondering if you might be able to get some help on this from birthmom. Maybe if your daughter heard the truth from her, it would help to counteract the lies the grandparents have told. I would also not allow further unsupervised contact with the bgrandparents. Before I allowed any contact at all I would have a very clear conversation with them letting them know why I am supervising visits and setting very clear boundaries about what is and is not okay.
