Hello my friend,
You have taken this topic very seriously and, as you wrote, by working with NGOs, you have also seen cruel incidents with children, which happen a lot in the society, while their reporting is negligible.
These are often suppressed due to fear of shame and humiliation. Your knowledge and experience in this matter seems limitless. But all I have to say is that if parents, apart from fulfilling their children's needs, also start knowing their children's mental dilemmas, then these distances and traumas can be reduced.
Wish you success.
With respect.
