Seeking expert testimony is a sign of strength. A personal relationship with a caring professional is proven clinically effective.
I believe that I can help
It may be the right thing to do, but if it is not effective then it will only increase your alienation from them.
If children are being neglected under the law then you need to speak up and if they do not listen to your warning then it is your duty to get legal help to protect them.
Overprotection is probably not covered under the law, but abandonment and negligence can not only cause them immediate harm but could cause them lifelong psychological problems.
Once again, ineffective action will not help. You must be able to prove your allegations and then the authorities can step in.
You have to consider your position with the family afterwards, but it is better to be shunned and protect the children, then to cower like everyone else who knows.
To sum up: act is you can help and make a real difference. It is not your job, but it is your moral obligation which is more important than a job.
I salute you for having a real conscience and be a caring family member.
I shall keep you and those children in my prayers.
