It seems to me that your mom might be trying really hard to find faults in your parenting to make herself feel better of her parenting faults. I think you are doing a fantastic job and it seems that the only reason you have CPS troubles are because of your mom. Either way I'd stay away from her too. You have many supporters here and it sounds like you have your mother in law there for you too. Stay strong and know that you have many people on your side. Hugs from Texas!!
