I have 3 stepchildren, they are 19, 18 and 12, all have the same mum (if that matters).
I have a son with my husband who is 2.
Middle SS lives with us and has since he was 10.
I've always had a really good relationship with them all, the older 2 had their moments growing up but they were just moments/phases just like any child!
But I'm really starting to struggle with the youngest, to be quite honest he just acts like a spoilt brat all the time and for some reason my husband seems to parent him totally different to all his other children. He's very strict on manners, behaviour with the older 2 when they were growing up and is the same with our 2yr old. But youngest SS just seems to be able to do and say whatever he pleases and it's really grating on me.
Just one example, today we had dinner with my mum, mum asked him to bring the plates from the table over to the sink, he just stood up and said do I look like your slave and walked off and sat in the living room. My husband said nothing so I said are you going to allow him to speak to my mum like that, he said he was joking, I said my mum asked him for help and hes walked off, that's not ok. His eldest son turned round and said I'd of never of gotten away with that at his age, so it isn't just me who notices.
I've discussed it with my husband and he says he isn't as well behaved as the other 2 as he wasn't around when he was growing up (his ex cheated when he was 6m old) so I said but that doesn't mean you now let him do and say as he pleases and allow him to be rude. He said he does tell him off; but he doesn't.
It's getting to the point now I'm just stating to dislike him, I don't want him to come at the weekend. He is rude to me and refuses to help with anything at all. I know this is a husband problem and I'm considering leaving him as this has been going on for months now and it isn't going to change when he's allowed to behave in that way. I just don't understand how he can be so different with this one child than he is with his other 3.
