My sons fathers wife has been in his life since he was about 7mths old. And now that he is 3 he knows who everyone is. She has taught him to call her mommy and i find that extremely disrespectful. I could understand if the mother was not in the picture however i am, and much more than her (80/20 custody). I have told her before not to have him call her that and she no she would never, but yet he does and she doesnt correct him. How do i address this situation or do i wait til he gets older since he will then know i am his mother and she is his step parent IF she is still in the picture.
