//Do you feed your young /teenager children before you go to dinner at someone else's house?//
When I had them, I wouldn't have dreamed of taking them to a dinner party at a friend's house, luncheon probably, but even then I would have checked before doing so, which imo you should have done yourself.
Are you certain the hosts said 'bring your family' or did you assume it? //
If you - and Sqad - read the OP, you will see that MDW is recounting an incident relayed by a work colleague, so he/she can have no knowledge of how the invitation was offered.
As I said, if my family were invited, I would assume my children were welcome, and would be eating with the adults - the host would have ascertained that the children were of suitable age before the invitation, otherwise it would have been for the parents only.
And as I also said, even allowing for a misunderstanding, the hostess should surely have had the manners to feed the visiting chilren, expected or not - that is simple courtesy.
To assume that you are bringing your children to dinner, but have for some reason fed them first, is bizarre.
