If you want to teach your children how to say sorry, you must be good at saying it yourself, especially to your own children. But how you say it can be quite tricky.  If you say to your children "I'm sorry I got angry with you, but …" what follows that "but" can make the apology ineffective: "I had a bad day" or "your noise was giving me a headache " leaves the person who has been injured feeling that he should be apologizing for his bad behavior in expecting an apology.
Another method by which people appear to apologize without actually doing so is to say "I'm sorry you're upset"; this suggests that you are somehow at fault for allowing yourself to get upset by what the other person has done.

A. she doesn't feel that she should have apologized
B. she does not realize that the child has been hurt
