How long do TPR appeals take????

Oh you are not going to like my answer. So I apologize in advance for ruining your day. ;(My kids had TPR Dec 2008. Yes 2008!!!! Mom appealled. Appeal went to higher court A YEAR LATER , judge didnt like the wording. 6 months later, it was back at the first court to be reworded. Now 6 Months later it was finally again in front of the judge in the higher court. We are just waiting for ruling. Oh and Mom could appeal again. Mom is in prison for another 4 yrs for homocide. The kids havent seen her since spring 2007. She was never given a plan. Nothing. Yet here they sit!
