While I fully understand the difficulties facing Social Workers and the absolute importance of the child being first priority, I think there is one aspect they underestimate: the damage done to the child by the undermining of family confidence. When dd's medical condition was misdiagnosed as possible abuse, the person who suffered in the long run was dd. She was not removed from the family, but she saw enough to realise that her parents were under suspicion, that people did not believe what she said but looked for underlying, more sinister explanations, that her whole home life was being questioned. Incidentally, the main suspicions in this case were not from SS but from the medical profession and the school. We cooperated throughout, we stayed (more or less) outwardly calm and polite and as helpful as we could, but it still took a dreadful toll on dd.
And naturally, however hard we tried, it affected our parenting in the years to come, and naturally that added extra stress for dd: it is stressful to be parented by someone who has lost confidence.
Six years later, dd was still school refusing on a regular basis, she started self harming and threatening suicide so that she would not have to go out into the outside world- when probed, she explained that she did not feel she could ask adults for the help she needed as that might bring on more suspicion. Extensive CAHMS involvement did little good as dd was afraid to trust outside professionals, despite the fact that we had asked for their involvement (so she wasn't getting those feelings from us). She gave nothing away during therapy sessions, because she was frightened of saying the wrong thing.
Of course, this is not a reason not to investigate. Investigations have to be done!
But I for one would feel a lot safer if the SS on the thread recognised that it is not just a case of child versus parent "and we don't need to give a rats arse about the stress of the investigation because that only affects the adults".
Ime the child is just as likely as the parents to suffer from the stress of investigation and those effects can be very long lasting. Anyone who is involved in investigations needs to be aware of that and take all possible precautions to mitigate the effects.
