Blimey, OmaforMaya, bit of an unexpected attack there!
The couple needed the help for their child and that is why they made the journey probably to their nearest relatives.
Their nearest relatives appear to have been Mrs Cummings brother and sister, both of whom live in London. Check a few 'facts' yourself before launching an attack.
And read lizzypopbottle's post and feel a bit of anger at the self sacrifice and distress that following the lockdown instructions to the letter has caused in one family, then imagine it repeated in possibly thousands of families across the UK because they too were following the instructions to the letter and didn't know about the instruction tucked in the bottom of a locked filing cabinet in locked office with a notice on the door saying 'Beware of the leopard', which said that if both parents are exhibiting covid19 symptoms and have a small child it is absolutely fine for you to pop yourselves in the car and journey 250 miles so that your elderly parents can take care of your child (the sister is a later variation on the story) while you isolate yourselves.
I'm not sure which instruction said it was then absolutely right that one of you should write a touching account of your isolation ordeal with one of you immobile in bed for 10 days and you having to have sole care of your child even though you're not feeling too good yourself. Without, of course, mentioning that you were doing all this 250 miles from your actual home... or that the supposedly immobile one was spotted dancing to Abba and wandering the local woods during that 10 days..
Reading around your topic is always a good idea...
