How do you respond when other parents speak negatively about their own children, especially in front of them? Recently I've had a few encounters with parents (that I did not know well) said things like "My other child is an angel. This one as a devil." or "Some days I just wish I could trade Child'sName in." The comments have been made in a joking tone, but they make me very uncomfortable and I feel for the children. I've tried responding by saying something positive about the other parent's child (such as "I really enjoy Child'sName cleverness and curiousity."), but somehow that doesn't feel like enough. At the same time, I don't feel like raising the issue in front of the child would be helpful. How have you/would you respond?
Thanks in advance!
