bootymum current practice has to do with a child's identity.
There was a time when a child in care lost everything, background, family contact, culture. Best practice would aim for a child to be with family whenever possible, or neighbour/friend, and so on.
Its the child's background and story, and whatever can be salvaged from an otherwise sad situation is important to keep.
People who adopt from other countries spend alot of time and energy getting to know the culture, etc of the area (Vietnam, Russia, Thailand, etc) and many of these belong to post adoption groups to preserve that side of their child's life, once they return as a family to the UK.
It is respectful at the very least. Even if you adopt a newborn, he/she will havecharacteristics that will indicate a history different to your own. Why hide that? Better to be up front.
I see that so much in adult adoptees who were denied any information and were even not told that they were adopted until they were adults.
Society has always helped to raised children for others. It was called kinship care. But thats another story
