I’ve decades experience as a CP social worker, each of the examples I gave happened during family time with a birth parent. No not all biological parents but violence followed by substance misuse remains the most common reasons for involvement with the child protection process, and for children being removed, between them representing over 80% of CP registrations.
I fully support children having knowledge of their birth families, and for adopted children having at very least indirect contact. I facilitate indirect contact for my own kids. I also know, from long experience, that by the time a child is permanently removed, the birth parents have had multiple opportunities over many years to show they can safely parent, or the concerns for the child’s safety are so significant and immediate it is clear there’s no going back.
Some birth parents can manage direct contact in a way that prioritises the child, and absolutely that should be supported where at all possible. I’d argue though that the majority they simply can’t because the reasons the child was removed are continuing factors in their lives, be that violence, substance misuse, etc and their lives continue to be too chaotic.
It’s funny - you routinely see posts on here from people wanting to cut contact with grandparents who have fed their child too much sugar, or who won’t follow their rules for their child. Or stopping contact with their dad because he keeps them up late, feeds them McDonalds or brought them home late.
But children who have already been significantly and often seriously harmed by their birth parents - to the point where professionals have evidence the parent cannot safely care for their child - should be compelled to have regular direct contact with that parent, because it’s their parent.
