MIL has just arrived from Indonesia with a stinking cold. She is supposed to be staying with us on the sofa for a couple of weeks. We've suggested she stay in a hotel for a couple of nights until she feels a bit better and we will pay half as we don't want to all get sick. DS2 is 18 months and constantly ill and he has a blood disorder that means he suffers more and can't shake it off as quickly. I know that keeping her out of the house won't guarantee we won't catch it and she may well still be contagious when she comes back but we're hoping less so. It's my DH driving this as he is a worrier and is always getting sick himself but he's feeling guilty now as he thinks she is upset.
