Mum is elderly with complicated medical issues, and was sheltered during initial outbreak 0f Covid.
Sister A (Anna) lives with her, but has a full time demanding job as a care worker in a major hospital.
Sister B (Brenda) lives alone, about 1/2 hour drive from Mum, has a full time job, currently (mostly) working from home.
We are at loggerheads over the government guidelines as to what is allowable at Mums.
Sister B thinks she is allowed to stay at Mum's, and to take her out sociably to lunch, shop etc, and to have her stay at her home, as Mum is part of her bubble.
As Mum and I are in Tier 2, I think sister B (Tier 3) is not part of her bubble, as Mum is not a single household, she has sister A living with her, and cannot visit outside her household.
A is not classed as Mum's carer, as she works over 40 hours a week, so technically is a co-habitee.
This has caused a massive row.
If anyone can shine a light I would be grateful
PS. Mum is sublimely disinterested - as far as she has company she is happy.
Bu this is causing major fallouts between the rest of the family.
