What to expect at TPR hearing?!?

Neither we nor our children were prepped for the trial. They had to sit through a very detailed reading of the abuse and circumstances of them coming into care. Some of it was very adult and the children (10,12, 16) did not need to hear it. The birth parents did not show up for the trial, so the evidence included the efforts cps made, and the parents lack of effort. The 16yo had to testify; he was very confused and angry that they made him talk "bad" about his mom. The judge gave his decision about a week later and then we had to wait a month for the appeal period to pass. Birth parents did not appeal. We then had to wait another year and a half to finalize our adoption (due to caseworker incompetence and financial issues with the county).
