Frustrated - Contested adoption

Hi. I have spent hours upon hours trying to find information regarding my situation. I have filed a Motion to Intervene, and Petition for Adoption for my 2 1/2 yo granddaughter. TPR has already happened. The maternal grandparents are the placement providers (I used to live out of state and she was placed with them). I am the paternal grandmother. They have also petitioned to adopt. So basically, we are fighting against one another to adopt. I know it sounds odd that two grandparents are fighting for adoption, but I am fighting to give her the best chance at a safe, secure childhood. There are several other reasons/stories I could tell, but that is not my purpose for writing this. The adoption hearing isn't scheduled for 3 more months. My lawyer and I feel that she should be spending equal amount of time with each set of grandparents, because there is a 50/50 chance of who the judge chooses for her to be placed with. With that being said, my lawyer and I feel, based on the evidence and information we have against the other grandparents for the hearing, it's more like an 80/20 chance in my favor. I have had visitation with her, at one point, a weekly 8 hour visit, and was told eventually I would get weekend visits. Then because the other grandparent caled the abuse hotline and claimed abuse in my home, my visits were changed and reduced. The investigation came back unsubstantiated, as I knew it would, however my visits were not returned to 8 hour weekly visits. The CD are and have verbalized their reason for reduced visitation is because "it's to protect me and alleviate the possibility of future hotline calls." This to me is completely unfair! Has anyone heard of or experienced this situation, or have any information of how I can be treated fairly by the CD? I believe an every other week schedule is appropriate. And while the hotline was being investigated, I had to have my 2 hour visits supervised and the CD workers saw how happy she was in my home and around me and my son. They saw how she didn't want to leave and how strong our bond is. Basically, I feel they are afraid of the other grandmother's wrath, because she is not a nice woman when she doesn't get her way. (That was a nice way of putting it). Honestly, I feel discriminated against by the CD.
