I agree she's being manipulated, but in all fairness the relationship between the family and the hospital appears to have broken down before their involvement.
As pp's have already posted, Archie's prognosis was known to be dire within days of him being in hospital.
The family then repeatedly prevented tests being carried out that would prove his brain stem was no longer functional.
By the time the courts were involved and the tests carried out they were too late. Again to quote a pp, he was too dead to be legally be declared dead.
Unlike the CLC the courts did not want to start changing the legal definitions/tests for brain stem death, so have gone down a route of best interests.
So yes, the CLC is certainly a very unhelpful factor here (and the rhetoric of him being disabled, which plays to the request for UN intervention looks right out of their playbook, rather than something Hollie would have come up with alone), but the family have been in "combat" mode well before they came on the scene.
Hollie seems to believe that her rights as a parent are paramount and that's simply untrue. How many news stories have we seen where parents have not only failed to protect their child from harm, but been the vessel to cause it.
Child safeguarding always means putting the child's interests first irrespective of the emotional impact to the family. Whether that means withdrawing treatment or refusing to move him to another facility.
Whatever Hollies motivations are and regardless of wether she believes she is acting in Archie's best interests, the fact remains that she has not been doing so for months.
It's absolutely not normal for anyone with a prognosis like Archie's to remain ventilated for days, never mind months on end.
ICU care is incredibly invasive and as professional as the HCP's are it is not a dignified existence having literally every single bodily function managed. It's however a trade off that's absolutely worth it when there is a prospect of meaningful recovery, but in this case there simply is not and every day Archie spends in that environment represents a great injustice to his personhood and dignity.
