I agree that he shouldn’t have been given his allergen. There is also a lot of detail missing. Was his dairy allergy known to be anaphylactic? Was he prescribed EpiPens? Did he have a set with him, if so? Did the nursery recognise anaphylaxis? Did they act promptly and call 999 (and give the AAI if he had one)?
My DC is at nursery with an anaphylactic allergy. Prior to them actually going into anaphylaxis from eating their allergen, we had no idea that it wasn’t a run of the mill hives and itchy skin, avoid this food but it’s not deadly serious allergy. None whatsoever. It escalated very quickly - and while everyone should know that this can happen, it’s not necessarily something you can deal with if it does happen and you haven’t got spare AAIs, for example.
That isn’t to say at all that it’s fine to feed children an allergen if you don’t think it’s a ‘serious’ allergy - quite the opposite, because they can and do escalate rapidly into something very frightening - but I wonder whether there was a lack of understanding of this, coupled with maybe no formal diagnosis/medication for Jude, a chaotic and careless environment, and just awful, awful bad luck that Jude’s reaction this time was so catastrophic.
To me, it seems like an example of Swiss cheese theory in action - if any one of those factors had been different, the outcome could have been very different. That said, the nursery is in control of two of those factors, and there should be some accountability for that.
