It is also an issue for children and young people who move to other foster placements. (As an example - some of our Foster Carers promised two young people when they left that they would never forget them and since then have always sent birthday and Christmas cards and small gifts. This year these have been returned because we are told that the young people are unsettled in their current placement. When we challenged this we were given the conventional wisdom!)
I also spoke to a Foster Carer today who is looking after a 16 month old and already trying to get himself emotionally ready for the inevitable departure, knowing that it is likely to be pretty abrupt.
