I've read the article again a couple of times, and whilst it's clear she lied about living with her husband, I feel a bit uneasy about any accusations of MBP (I'll probably be flamed for this!)
On most of the threads like this there are always a few, including professionals; teachers, Drs, etc who claim that a child they know definitely doesn't have ASD (for examples read this thread again). There are also professionals in observing roles who are not experienced enough to spot the more subtle signs a child might show, especially when masking. For us this included the NHS clinical psychologist, although she did actually see the signs but left them off the report. It is also fairly common for parents of DC to be autistic themselves, perhaps without knowing. This can lead to different behaviours during assessments and medical appointments which may start alarm bells. This leaves some parents wide open to accusations of crap parenting and it's not unknown for some parents to be falsely accused of MBP. I was particularly persistent during ds's assessments, with support workers who knew bugger all about ASD, and this backfired on me, although not to the point of MBP accusations, but enough for the whole thing to be really fucking traumatic. I didn't lie at all throughout the process, but it was assumed that I did.
Re. the feeding tube, this isn't something I know about, but I do know a couple of DC who have feeding tubes in but can still eat normally, unless these DC,s parents also have MBP there must be some presedence set for this to happen enough for me to know 2 DC in my limited social world who have a tube and can (and do) also eat normally. Happy to be corrected here.
I'm sure there's more to this case than has been reported, or maybe I haven't read closely enough, but with regards to MBP, or if not that inventing medical conditions for financial gain, well, on the information we have, I do feel uneasy about it. DLA is not easy to claim and needs lots of evidence from professionals. Autism diagnoses are not handed out to anyone who asks for them.
I may be completely wrong here, but this has bugged me since reading this earlier today.
