I wonder if we're getting a bit lost here with the discussion of FII/MS by proxy.
Re-reading the original Telegraph article, the evidence for FII/MSbP seems to be based on the single paragraph quoted from the paeditrician's letter. I'll quote it here to save everyone looking for it:
"Even in the absence of a psychological assessment, if the professionals were concerned on the evidence available that Miss Holton (as Miss Lyon was briefly known), probably does fabricate or induce illness, there would be no option but the precautionary principle of taking the baby into foster care at birth, pending a post-natal forensic psychological assessment."
After re-reading this several times, he seems to me to be saying if other professionals (doctors? midwives? mh workers? We don't know) have evidence that FL probably does fabricate/induce illness in herself, then best put the baby in to foster care until you can do an in depth psychological assessment.
The first point is that this isn't a description of FII/MS by proxy it's a description of Adult FII/MS - which has been known about since the 50's and well documented and researched.
Secondly it seems to me that he is not making a judgement of Fran's MH, as he says a forensic psychological assessment should be done. What he does seem to be inferring is that his experience of the effect on children whose mothers fabricate illness in themselves is such that he would recommend erring on the side of caution until Fran is adequately assessed.
Obviously it's hard to be sure because there doesn't seem to be any more of this letter reported and so we only have this single sentence to go on.
Am I reading it all wrong, or does anyone else read it that way?
