Friend has been with her husband for about 4 years and they married earlier this year. Her DSD is 8 and they have her every Thursday and every other weekend.
She mentioned to me that DSD accidentally called her Mum the other day and she told her if you want to call me Mum that's fine. She said DSD didn't really respond.
I said oh I don't think you should encourage that she has a Mum and it's not really fair on either of them to say that to her. For context I am a step mum myself, have been for 10 years and I also have DD, so it's not a judgement thing I just don't think it's a good idea!
Well she is fuming with me, apparently she is entitled to tell DSD to to call her Mum and I am bang out of order.
I have apologised and said I didn't mean to offend her but things are still a bit tense.
So was I unreasonable?
