I agree that teaching manners is important. But it is an ongoing process that involves lots of practice. I donot expect my young children to always say sorry, please, thank you, excuse me, etc... every time. I do not expect others to be perfect either.
I think that as her parent
I need to be sure that I am modeling the type of politness I expect my children to use. If I expect them to say I'm sorry for accidental bumps than I need to be sure that that is what I say to them. If I expect them to say I am sorry after acting agressivly whith another child than I should be saying I'm sorry after I am agressive with them.
I have always said please and thank you with DD, even as a baby. I remember distinctly useing thank you with her when as a baby she started the hand Momma every toy game. I remember using please when I needed to take something away from her around this same age. DD started spontaniously saying please and thank you when she was verbal enough to say a 3 word sentance.
Sorry is a much trickier word since it is used so meaninglessly by so many in our culture. I think DD learned to use it because as a toddler she would hear me say it when it was appropriate. If she hurt another child during her play I was quick to appologize to the other child (and the parent). I did not make a big deal over DD apologizing, instead I would see to the hurt child's needs then take appropriate action with DD (weather it be redirecting play, removing her from the situation, having a little talk, etc...)
At 5 DD uses sorry in 2 ways. 1) To let the other person know that whatever the action was that caused an upset was not intended. For example: playing with blocks and she knocks over someone elses structre causeing upset. She's pretty quick with I'm sorry. 2) To bring closure to an incedent and reenter play. For example: She got mad and pushed another child on the playground. After spending some time calming down (and me doing what I need to do as a parent) she will usually go back to the child and say I'm sorry, are you OK, can I play with you again. At first she needed me to be there guiding her in this process.
In the second example ther is a space of time seperating the incedent and the appology. It seems to me that this may be a key differenece between an appology being forced and feeling uncofortable for all parties and an appology that is sincere.
