Is it normal for my step daughter to...

These comments make me angry. She needs help. 8 year olds don't just lie about being sexually abused. If they do, they probably are being abused sexually or not and aren't giving all the details. Why? They're 8.
This is a huge developmental stage in a childs life, and abuse can really fuck with a kids brain.
I was diagnosed with a personality disorder at 14, and my psychiatrist thinks it's due to the abuse I endured from 6-9 years old. It's very common, and effects different people on different levels. Apparently, it affected me severely. It sounds like it affected your step daughter even worse.

I'm with you bubber - video tape it for evidence.

She sounds psychologically disturbed, you and your partner need to get to the bottom of this before she hurts someone - your baby is too precious to risk it.

Get her diagnosed right away for autism, Aspergers, trauma, whatever it may be. This little girl needs help.

You're gonna have to videotape this as evidence if you want your husband to believe you..

She is the spawn of Satan. I'd start worrying about who your partner really is.

She is either a sociopath or she really was abused and has simply become a product of her environment. If the latter is the case then it's best for her that you all took her in so that maybe with tlc, she might be reformed and become more normal. You have to think of not only your babies self interest, but also the best interest of this poor child who has obviously not been loved or looked after properly. She is so young. She deserves better and since she is so young it will be easier to help her change into a decent human being. It could also be that she just doesn't understand some of the things that she is saying. Most children aren't even spitting out their own ideas or opinions because children's ideas and opinions are based on what they know. She is most likely repeating things that she has heard. I'm not saying that you shouldn't be worried about your new baby. Protect him and keep a careful eye on him around her. But don't let her attitude keep you from treating like a child should be treated. Don't alienate her. It will only make her worse. She needs love.

I would check her for a strange tattoo or birthmark that resembles "666". You should also watch the Omen. It might be educational....

Seriously, though. Her dad probably is ignoring it because she's his little girl, but if it's like you say, this kid needs help...maybe a hospital stay at one point. You have to put the safety of your baby first.

Protect your child. If your partner sees no issue with what is happening then you need to get out of that situation. That girl needs help but if the father condones her behavior then how can anybody help her?

Worse, if he's perfectly fine with raising his 8 year old that way, then what will happen to your newborn?

She has issues. Protect your baby around her..I agree. Worry about who your partner truely is an and video tape her.

She's a little shit...but she is still a child with some serious issues. Also, for her to even know what sexual abuse is at such a young age screams that something isn't right.

It sounds to me like she has been abused. I'm sure that this is not what you want to hear, but you and the therapists need to consider everyone in her life as the possible culprit(s) of her abuse (ie her mother, father, older siblings, mother's boyfriend, etc). She clearly needs intensive treatment, and since you are aware of the severity of the situation, I urge you to really make a push for treatment. She's obviously not getting what she needs from you two alone. Hopefully, if she gets with the right people asap, she can get on track to being a healthy, happy kid an adult. Good luck to your family!

She needs help. Usually I write more, but that's all that can be said. It's one thing to be shaken up by a divorce or remarriage, but that kind of behavior is completely unacceptable.

Try and talk to her, ask her about her past and what she likes, try and get close to her so she trusts you, then if something happens she will listen to you.

This makes me think of Damien in The Omen

I thought this behavior had stopped and today she suggested we kill my newborn. She suggested this seriously without a smile or laugh i didnt even no wut to say. I told her you cant just kill people and she asked why. Then i explained about murder, and jail and nut houses and she ssys ohhhh. Wtf she is so screwed up

This girl needs help. Try to find someone to help her adjust.

Instead of being protective of your baby and denying her. Why not try to involve her more. Remember people meet aggressiveness with the same amount of aggression. It might be hard, but if you're able to include her as a family and treat her as your own. You will be a powerful mother to your current baby. Remember to love.

She needs counseling! Sounds like a cry for attention/help! You'll regret it if you don't get help for her!

no way man she probaly got isssues herself u need to check her out at the hospital dont be scared just help her xx

she definitely needs help. i agree with everyone else, something's wrong with her.

Aww satan the little bitch is back

The chair part seemed pretty funny to imagine.

For me it sounds like she's been abused she's taking it out on the baby. and on other people who are as you could say useless like mentally challenged student you mentioned. :( I am young I am barely freshman but intelligent and have a lot of common sense. There's price something disturbing her. it sounds like she has a lot of anger, and she was probably jealous of you. try to talk to her or have your partner talk to her. have a family meeting try figure it out
good luck.

why don't you just dump her on the street in some random town she's never been to

She needs her ass whipped! Sounds like a spoiled brat that has to much control for a child.

sounds like shes an evil bitch, or else maybe ur depressed frm the pregnancy or paraoid.. i duno lol but if all tht really happened she is one fucked up lil kid
