SS has started insulting bio dad, fine with us though

[Markb123]

Just wondering if anyone had come across the following, I'm a are step dad and my SS is fine with me and my DP, but now we've found out when he goes back to his dads he is calling him names and generally acting up. He is a really good dad and I don't want SS to act up with him, any tips?

The title of the post doesn't really match the content - is this a wind up?

No not a wind up, wasn't sure how best to word it, essentially my step son is fine with me but with his actual dad he's recently started insulting him and acting up. I always thought it would be the other way round really. He's 8 by the way

Ah sorry - I thought you meant your SS was playing up at his father's home, and that you were fine about it!

I'm not quite sure why his behaviour at his 'other' home bothers you, if he's ok when he's with you?

My DSD is usually fine with me and not so much with her Mum. We have our moments but she's never actually screamed at me in the way she apparently does with her Mum. I think it's probably because she knows I'm a step-parent and not obliged to put up with it in the same way that her parents are. DH is very strict so she wouldn't get away with it with him. I guess her Mum is where she lets off steam!

Same my with my DS. Brilliant at school, brilliant with pretty much everyone else, slightly less brilliant with DH but a right little stinker with me...
