This is the perfect example of what NOT to discuss with your kids man, seriously. If you take this approach, not only will it just sink in for a day (and your 5 year old is going to have no idea what the F you're talking about anyway) I certainly hope you are ready for the fall out.
That little presidential address to the union of a 5 and 8 year old there is a prime example of how to paint the other parent the bad guy, an A NUMER ONE NO-NO and will do more damage than good and potentially turn them against YOU for defimating their own mother! Yeah, there's a point in it's own, she may be your ex-wife BUT: She is still their mother
NCB, if you really feel inclined to say something, keep it simple (read as on a kid level, not doctorate), just as I did to mine where the listening ears were 10 and 11(really about 7): "hey guys, dad can't control what what happens and who is around at Mom's place. Unless you feel you've been hurt or wronged in some way, dad doesn't really want to talk about it, ok? Let go get some ice cream!" Done!
