I only caught the last 20 mins or so, but I was in tears twice. The first time when the mum kissed her little girl goodnight for the first time in years, but could only manage this when she was asleep. And the second time when the dad (who had had his daughter later in life) was explaining that he thought that people didn't want to let their children come to his daughters birthday party because they saw him collecting her, and thought he was some sort of disreputable character.
I could see that the gist of the parenting advice they were getting was that their behaviour impacted on their child's behaviour, and I was really pleased that they seemed to stick to it and improve the situation. Was that the overall tone of the piece or have I misinterpreted?
