PECS, finally, a voice of reason. We've all had an 'Auntie Gladys', and I'd respect any parent who gave her a bit of telling off if her over-exuberance upset their child. But, really, there is a gross difference between what the OP mentioned, and what some others seem to be interpreting it as, which, frankly, all sounds rather over the top in some cases.
Perhaps it is some of the mothers who have issues that need taking care of, before they pass on unnecessary fears to their offspring.
As PECS said, children need to develop social skills, and they won't develop those fully with only having contact/interactions with their immediate family. It seems that even some grandparents are not allowed close contact with their grandchildren these days, because of over-protective mothers. Every mother wants to protect their child, but some really do need to lighten up a little.
