Hon, that's his daughter and that won't change. You will always be the big mean bully and she will always be the poor princess. Can you live with this?
What happens if BM dies? Can you live with his spawn 24 hours a day? It happens. We've got a few women on here that went from EOW to every dang day.

I can totally understand where you are coming from, because I have been in a similar situation with my eldest SS - BUT he was much older at the time (14). Looking back, he had been living full-time with his dad (his two younger brothers lived with his mum) and I think that when DH and I got together (with my three children living with us full-time) he probably felt jealous and threatened because he suddenly lost all of the one-to-one attention and was having to share with three new step siblings and a step mother he hated.

Because your SD is so young still, I wonder if you could turn this around. It will be really hard and you may have to man up. I think her behaviour is insecurity and jealousy. She probably is totally aware of the fact that you hate her and consequently probably feels scared of rejection - so constantly seeks attention.

Could you make an extra special effort to try and bond with her? It will be hard to get over your prejudice (I know I never have with my SS and still can't stand him - but he's a grown man now). With such a little girl, perhaps if you took her out and gave her some one-to-one time - maybe shopping or get your husband to look after your kids while you take her out to the park, or ask her to help you with baking cakes or something. Maybe once she feels that she is liked and not in competition with attention from her dad she will calm down and everyone will be happier. It will be especially easier for you when the baby comes if you can cross this barrier now. Difficult as it is, you have to remember that she is a very little girl and you are the adult - this situation will only change if you step out of your comfort zone and make the effort. Good luck.

get your kids to start acting like her, and see what DH says then.... maybe he will realize he's a disney parent and maybe he will start parenting his daughter and not treat her like a princess

Ss13 used to walk in between us while talking All the time... it did not bother dh till ss got taller. If we were talking and ss blocked us id just turn around and walk away. If the convo was important dh would follow me.
Once ss head started blocking my face, dh finally, finally started telling him to get out of the way.

Its weird how men do not deal with things till it really effects them.

Either way hating her is awful to read.

I know your annoyed...irritated... frustrated, but try not to hate a 6 year old.

But worry about that baby, if she is stressing you out, go upstairs lock the door and dont worry about dh and her...

Hugs...

After the baby her behaviour will probably get worse.

When our baby came home omg the first month, ss was talking like a baby saying he loved everything PINK, was in dh lap, if he was around while people were talking about the baby he immediatly talked about how,she was like a dog or puppy, and try to talk about how cuute he was....ughh. and he was like 10 or 11...i just had to wait it out...leave the room...whatever to keep my sanity.

I can't stand her voice the sight of her nothing !

And you still got pregnant by her dad and put yourself in a situation to be around her A LOT. I DO NOT UNDERSTAND THIS AND IT HAPPENS ALL THE TIME HERE!!!

What if BM dies? You will then be a full time SM. I don't normally recommend divorce but your hatred for this kid is over the top and maybe something you should think about. Or at least living separately until the kid is MUCH older.

She is acting pretty normal for her age and is pushing boundaries. Your DH is the one to not correct them so yea...you are angry at the wrong person.

I can't imagine this 6 year old suddenly started acting poorly. I would assume this has been going on since she could walk and talk. So I'm confused as to why you married your DH? (without say "you knew what you were getting in to") Did you think she would grow out of whatever silliness she was presenting? Or did you have hope that your DH would step up and parent? How often do you have her for visitation? Does her BM facilitate all of these behaviors?

I know that a lot of people disagree with me and I hate to say it but I think 95 percent of us knew what we were getting into. We just had blinders and thought we could change things or we thought DH would start to parent right as soon as we get married. It is human nature to do that and have blinders on in the beginning.

But for someone to have this much HATE for a 6 year old….she HAD to have known the deal when she married or knocked up.

Unfortunately, I don't think it gets better unless your DH is willing to do something about it. But, since she is only there 6 days a month, I doubt he's going to do anything to upset her. My SS is also sensitive, whiny, bratty, and manipulative. My negative feelings for him grew during my pregnancy. I thought it was hormonal and that those feelings would subside, but SS has just gotten worse, so it's hard for me to feel empathy and caring towards him. I fake my feelings with him. The plus is that DH started to really parent the skids before I had enough. The negative is that it took a long time and it took us having the skids full-time for him to make changes. He could no longer stand their behavior either when he had to put up with it all the time and had a bitchy wife to deal with too. I was also as straight forward as I could be about the odd/disturbing behavior that the skids displayed. DH trusts my judgement, so he made changes. I say, fake it til you make it, when it comes to acting around the skids, if you are trying to keep things civil in the household. For me, it's just always faking it. I'm cordial, but I'm not responsible for him.
