Does her Doc... know that... she resides with you AND that you have young children, one of whom is a baby?????
If not, I would talk to the Doctor, personally... and ASK all of the pertinent questions and concerns.
Because, sometimes with a very contagious infection/disease... young children cannot be exposed.
The Doc, needs to know that one of the children is UNDER 2 years old. Or anyone else with compromised immune systems or in poor health themselves. For example.
Your Mom... should not be at home, so soon.
And, is bleach, even effective, in this case?
I would seriously talk to a Doc or someone higher up the food chain. About it.
Now... in the long term... your parents are living with you.
Your Mom... has serious health problems. You are not a nurse. Your Husband is not a nurse. You have 2 young children.
Let me tell you... that care-giving... for an ill parent.. is VERY hard.
I know. I did that for my late Dad for THREE years, until he died. But.. it took me/my Husband AND my Mom... ALL tending to him, 24/7, day and night. I did not work at that time. Because, someone had to be home.... with him, due to his health problems.
It is not... easy. It is very hard.
You SERIOUSLY... need to think about what is best for your Mom. And that is... having medical care... or a Nurse Aide or something, to care for her. You or a layperson, is not equipped for that nor with the medical knowledge... to take care of her.
You really, need to think about this.... and with any siblings you have. You should not have to be the sole... care-taker. And, it does put a lot of stress, on the other family members.
Take care.
