If you are going through a divorce, or are just upset with someone watch what you are saying about this person while you are in front of your child/children.  Especially if this person is someone that your child cares about.

It hurts your child to hear bad things said about someone that they love and it also may put them in an awkward position.  If you are going through a divorce it is even more important to keep your feelings to yourself about it.  It is not the fault of the child, and he/she needs to know that even though the parents are going to be separated, that they are still loved by mommy and daddy.
