There seems to me a general lack of ignoring a great deal of evidence that's actually relevant here.
I will clarify I'm not in any way medically trained but I do have a lot of experience of DS.
Firstly a child isn't generally taken to a and e for D and V. It's advised not to. This to me would indicate overall health concerns from the parents - maybe because of the DS?
That the parents chose to give the medication and seemed to seek dr advice until they got the answer they wanted - which was to administer it if they wanted.
A child with DS and heart defects can be at greater risk of chest infection which I believe they sought tests for?
This wasn't one DR providing a lack of care but a busy understaffed peads unit and a very sick and vulnerable young child who didn't present with the symptoms he later died of.
I understand his blood gases were raised but no one got this info - again due to failures of system. But I understand later bases showed improvement and that isn't being reported so much?
The whole situation has be bourne out of an angry grieving mum and and NHS happy to scapegoat 2 staff members and a justice system who didn't hear all the evidence available from the internal report.
It's a very close line pushing these criminal charges as it's leading more towards the expectation that Drs should be God's.
We already have a problem with recruitment of nhs staff (alongside teachers which doesn't surprise me either!) and it needs to be rectified from the government downwards.
I don't think it'll happen though all the time we have a government that thinks only people who can afford private are worthwhile.
