My situation must be pretty common - I am single and I care for my adult son who has LD. as we are two adults in the house, I can't bubble with my parents - also two adults in their house. Before covid, I depended on them a fair bit to help out with my son - who they love being with.
If my son was under 18 - a child and going to school and mixing with 100s of other kids, we could bubble. If he lived alone but had a team of carers coming in, he could bubble. But in our situation we can't.
This seems very unfair to me - shouldn't there be an exception made for unpaid carers?
