Chicken pox in house with 6 week old

[Littlejayx]

I’ve googled everything about immunity and breastfeeding giving longer immunity to chicken pox but I am worried!

Has anyone’s school age child passed chicken pox on to a newborn/under 12 week old?
My 4 year olds pretty much whole class are off with the pox and my daughter picked it up this week, I’m trying to keep my daughter away from the baby but I know she would have had the infection for a while.
I had chicken pox when I was 18 and Breast feed my baby but am so worried about my little boy catching it!

Any real life experiences?

My eldest had the chicken pox when my youngest was only a few weeks old. Thankfully she didn't catch it. I tried to keep them apart as much as possible, still in the same room but no cuddles. I spoke to doctor about it tho because I was so worried. He said that if she did catch it it would probably only be a mild case because I was breast feeding so she would have some of my immunity.

My DS caught when I was BFing. He got about two spots and that was it.
