she's six. its normal development.
just keep modeling more acceptable responses.
if she seems to be having trouble understanding what is offensive to the other kids you could role play being kids in various scenarios. just keep it brief and simple and dont dwell on it.
you can also read books with kid interactions and ask her how the characters feel about certain things and let her talk. dont judge her responses. you want what she thinks not how she should think.
you can also gradually move into has she ever felt that way questions and then carefully into have you ever made someone else feel that way.........
We also used to have discussion about being a good hostess at that age.during play dates I could just ask are you being a good hostess? or do you think your guest is having fun? sometimes that would change the tone.
