My almost 3 y o daughter refuses to say "sorry." She will push her sister, go on time out but won't apolagize. Even when she hurts someone by accident she won't apolagize. I will keep her from getting to do a desired activity until she says sorry but she is pretty stubborn. I also model for her e.g. "you really hurt suzy, how does it make you feel when someone hurts you?" I really praise other children when they say sorry.

Do you make kids say "sorry?" What else should I try?
