My parents are 70 plus, with blood and breast cancer. They also live in a similar setting with us.
I am also pregnant and we have an under 2 year old.
DH and exW both decided it was safer for all (as my mum is going for radiotherapy daily at hospital still) that we make sure we do daily video calls until all this is over.
Sharing god knows what between two households isn't beneficial for anyone at all. For either of the SCs homes, or the knock on effect that could bring.
Least of all the vulnerable directly, or indirectly involved that could lose their lives.
We will miss them naturally, but people actually staying alive and as healthy as possible (including the SC) is far more important and this won't be forever.
My cousin and her ex have also decided for the sake of their mutual DC that they won't see him for a while to minimise risk.
As has my friend with his girls on mutual decision. Youngest is on the vulnerable list and he works in a supermarket. He realised he woild be putting youngest especially at risk and both parents decided on keeping them with mum until a later date.
This is a very unusual time, risk factors need to be thought of. For everyone. It's hard and its shit, but everyone needs to play their part in keeping the vulnerable safe so that in turn it keeps everyone else safe.
