I'd go will both Guests.
Haven't had kids round quite so bad, but when they know YOU have boundaries which it is not acceptable for them to cross, they usually learn very quickly not to cross them, and praising good behaviour ignoring/playing down bad helps reinforce.
If that doesn't work then a less tactful approach of telling the parents they are welcome but the brat isn't might be needed. Might be what they need to prompt them into dealing with it.
Totally agree. I am a firm believer in the method that G55 advocates but I also will not tolerate bad behaviour from anyone in my house (including me!
I know that the parents of this child are also in your family but, in my opinion, parents who are helpless are parents who have given up. There are two children like this in my family, with lovely parents who are unfortunately totally clueless when it comes to discipline.
These are doing such a disservice to their child, it's not the child's fault that she isn't disciplined but it's the child that other people will dislike. It's very sad. She is just a child after all.
