John Hemming, thank heavens you are helping 'Rachel'. I do hope somehow the legal process makes sure the adoption doesn't happen while the mother is still fighting her case - although having followed similar cases, I'm not confident about that.
One of my friends is a neonatal nurse. I have the impression from chatting to her about her job that short visits are not unusual. Very stressful environment for parents, who can feel like there is nothing for them to do, the nurses are in charge and meeting all the baby's needs.
Sadly, she often has to look after babies who are perfectly healthy but SS are involved - presumably with reason, I don't know and neither does she. Just has to look after the babies while SS go through whatever procedures they are going through.
