Based on my personal experience with families that I know, my statements are 100% true.
This will take us on a tangent at this point so I don't want to derail the thread too much by sharing multiple situations. But I can assure you that it doesn't take anything for CPS to get involved. I know a woman whose mother in law didn't want her birthing at home. The night the baby was born she called the police and they came with CPS and too the baby and it took months for that mother to get her child back. That's just one of a handful of which I have personal knowledge of the family.
