Interesting that article refers to another case of a baby who was put up for adoption because she had been separated from birth mother for too long, even though mother was cleared of any wrongdoing - social workers delayed too long.
My BIL and SIL had exactly the opposite experience. They fostered a little girl from birth until the age of 2 with a view to adoption. BM did not want the child and always maintained that she did not know who the father was. Then, just before the adoption was due to be finalised, she suddenly came up with a man who she claimed was the father and the child was taken away from BIL and SIL and handed over to this man. He never had to prove paternity, the BMs word was taken. This despite the fact she had never mat this man, called BIL and SIL " mummy and daddy".
BIL and SIL are not allowed any direct contact, but are allowed to send cards etc.
This completely destroyed them both and it still hurts now, 7 years later.
It just shows there is no consistency in approach so stupid decisions are made that are definitely not in the best interests of the children.
