Sorry Nigel, I am not buying that.
That's ok. I'm not selling anything.

Cummings put a young child in a car, a very confined space, with a known sufferer for several hours.
Rather than staying at home with that same sufferer.

He travelled 260 miles to his parents house. Now I am guessing as he is aged 48 that his parents will at least be in their late 60's or early to mid 70's. That is they are people classed as being vulnerable.
Not to stay 'with' his parents, and the intended carers for his child (as mentioned by Steve) were young nieces.

So not only did he put his child in jeopardy he also put his parents in jeopardy.
Only if they (any of them) were making close contact with those elderly parents.
