Posting here for traffic sorry. And it's a really boring aibu. 
So we're meant to go to dinner at mil and fil tonight.
Sil is also meant to be coming with her two girls.
Wednesday dn got a fever and rash has broken out today so she has rosella. She's almost 3 and actually had it last year too.
Other dn is 1 so probably brewing it right now although seems fine.
My ds (4) had it when he was 1. Dh doesn't want to go to dinner in case he catches it again.
I think he'll be fine as from what I've heard it's not contagious when the rash has broken out and the other doesn't have a fever yet so probably isn't contagious either.
My whole argument about it being fine is falling down with Dh somewhat as both dn and I have had it twice (I had it again a few years ago.)
I'm usually the first to avoid getting ill if we can help it but it's really uncommon to get rosella twice isn't it?
What would the wise Mumsnet all do?
(I have a feeling dh just doesn't want to go
)
