My in-laws are fit and healthy and early 70s in age. My own parents are slightly older, DF has heart disease etc. My parents are staying at home and taking the advice seriously and not going out. We've said we'll see them on the other side. My ILs, however are adamant that they do not want to live like this. They aren't going out (other than to the local shop and for walks) and are shrugging off our concerns for their health and well-being. We want to keep our kids away from them so that they don't get ill/ die but we can't seem to get through to them. They pick our son up from school one day a week and insist on continuing to do this. They've had a tough year... MIL has lost both her parents in the past 6m and a good friend last week... so they want to enjoy every moment, which includes spending time with the grandkids. How do we manage this? Do we let them crack on (their preference) or firmly insist that they don't come anywhere near us?
