Spiteful step daughter

Natasha90 · 17/08/2025 09:12

My 16 year soon to be 17 year old step daughter is just making our home so miserable.
she has lived with my husband and I since she was 10 and previous to that my husbands mum
She’s had no contact with her biological mother since 8 years….

we have always over compensated and she’s always had everything she wants.

I struggled with infertility for years and was blessed with my baby boy late May after a few rounds of IVF. When we told her she was hysterical crying awful.

Ive always treated her as daughter everyone knows me as her mum. My family have all welcomed her.

NYE just gone at a family party when people was asking her if she was excited she was rude and said no she don’t want me to have the baby etc.

We have included her as much as we can gender scan, she was the first person to meet him when he was born.

i thought we had turned a corner but she ignores the baby when it’s just me and her at home. She’s off for the summer….

She has always been rude and abrupt but this is another level. We have stopped her disposal money as she was very spoilt.

She can’t keep friends this has always been the way since young. She talks over people and belittles them and then wonders why she is on her own it’s sad and I’ve always explained why this maybe however she can’t see any error in her ways.

Aged 11 when she started secondary school, within the space of 6 months she went to school covered in fake blood, faked and overdose to her friends, faked and eating disorder not normal child behaviour at all.
Then she made a friend group which was fabulous however they all self harmed, she was then stealing money and other stuff out the house.
I had been in the school several times at this point and got her cancelling to which after the 3rd session she wanted to quit because she actually said in front of me and her teachers she does it with friends for attention…

back to the baby - when people are in the house visiting etc she will be all over the baby take him off other people etc

when it’s me and her she does not give him the time of day at all. I have tried a number of things like can you watch him quick whilst I hoover etc. she calls me after a minute.

she also says when her dad comes home from work the baby has been crying all day - he hasn’t ?

she had a set of drawers in her room that have been empty for months so I said when she’s away on holiday (this week ) I will put mine in as my husband and I the baby are fighting for space in our bedroom. I’ve gone to do it and she’s filled them up…

I was gifted a food blender thing for Christmas which was being saved for when the baby was eating food. This has been discussed on several occasions literally 4 weeks prior. I went to visit family on the day I left she’s using it.

My friend bumped in to her and asked how the baby was she rolled her eyes said friend - embarrassing 😢

I know the above sounds like minor things but she’s due back tomorrow and I’m dreading it I feel so anxious.

I have tried to discuss with my husband and said about the drawers and the smoothie maker etc and he thinks I’m just being silly. When we are all here she’s in her bedroom comes down the stairs gets food / drink goes back up does not say hello etc. when we say why don’t you speak to us she says we should speak to her first!!!

I don’t know if my baby is safe around her. She keeps carrying him in to the garden on the patio and holding him with 1 hand I explain his more mobile now and keeps moving you need to hold him with 2 hands she does not listen

She ignores you and the baby and also takes him in the garden?

You want her to greet you but you refuse to greet her?

You have equipment in the kitchen that the whole family can use but no one is allowed to because it's for the baby, it's been sitting there since Christmas?

The child you say is spoilt, so you have stopped her allowance but you and her dad always over compensated and gave her everything she asked for?

No wonder she's confused.

Summeriscumin · 17/08/2025 09:23

Please do not leave her alone with the baby. She sounds very disturbed and your husband has to take it seriously.

maybe it's time she moved out.

Natasha90 · 17/08/2025 09:24

When me and my husband are in the garden she carry’s the baby from his bed and brings him out in the garden

The blender was packed away in storage cupboard not on full view!!

We have limited her allowance not stopped. She used to call / text for up to £100 a week now she has a set allowance for a month !!!!

Our daughter intensely resented her 9 years younger brother when he was born. After years of being an only, I think an element of that is to be expected. It dissipated when he became a toddler. Adults now, they couldn’t be any closer.

purpleme12 · 17/08/2025 09:28

Maybe she does need some help but the blender thing is strange thing to mention as what's the big deal with it being used? Surely it can still be used for the baby! What's stopping that from happening?

Also the drawer thing. I think it's normal that someone doesn't want someone else's things in their bedroom

Tiswa · 17/08/2025 09:28

With respect you k know that she has been a troubled young girl but you have done NOTHING. Neither of you have parented her or helped her through any of this with any form of intervention and now your plan is what?

some of it the eye rolling etc is normal as is the fact she was going to react badly to the baby being born - she was never going to be as excited as you

family therapy, possible look at ND behaviour should have been done ages ago

GlastoNinja · 17/08/2025 09:30

This is a girl with emerging mh problems, probably underpinned by attachment disorder, get her back to therapy is my advice. Someone experienced with attachment.

In the meantime she needs consistency, love, respect, clear boundaries

There is the same age gap as them between me and my brother and then I have another one 2 years younger. We are so close in like a second mum.

everyone thought a similar relationship would be established.

how long did it take for her to come round??

Gradually over 18 months or so I think (long time ago now).

ElCorazon · 17/08/2025 09:32

Why have you always overcompensated her? Just because she is not in touch with her biological mum? (Btw was it her choice or the mum’s? What happened there?)
You do not have to overcompensate children for anything, it’s enough to provide them with a loving and stable family background. I think you spoiled her, she is a massive attention seeker.
I bet my bum someone will come and say she needs more love and attention and she is just a poor child who is confused 🙄

Never trust her with your baby, don’t let her handle him.

I can only assume this is trolling because otherwise it is such an extreme and stupid comment it’s pretty grim to think real people think like this.

RattyMcBatty · 17/08/2025 09:33

Bit odd that you have a blender, but no-one's allowed to use it until the baby starts eating blended food. Why on earth not??! That's one way to make her feel less important than the baby.

Also, bit odd that you think it's okay to put your stuff in the chest of drawers in her room - what were you going to do, just walk in her room willy-nilly whenever you wanted something out of there?

ARichtGoodDram · 17/08/2025 09:34

Has she had proper counselling to deal with the feelings she'll have about not having a relationship with her mum?

I think you've been quite naive not to expect this tbh. She's going to test every single boundary and line as she's fully expecting that now you have your own baby that is properly yours you'll abandon her.

It's very different to the situation with you and your brother (unless you've missed out your mum not being around). He's your actual baby and she's not - she's not feeling remotely secure that things haven't, or won't, change now.

CatRescueNeeded · 17/08/2025 09:35

What do you mean she should move out. She’s 11 - where do you expect her to go? You expect her father to kick her out now he has another child with another wife???

@Natasha90 - you really need to start thinking about everything this poor girl has gone through and how insecure she must feel now her half-brother has been born. Why are you picking over small things like using drawers in her own room (who would want their step
mum wondering in every time they needed a new T-shirt£ or using a kitchen appliance?

Wow the blender was a gift for me for Christmas…. It was me and her dad who said we would pop it away for when the baby is weaning. We do have another perfect blender out in the kitchen which she’s never used in her life!!!

we had the conversation before she went I said I would get anything needed the previous night so I wouldn’t disrupt her. She was fine when I asked….

She does sound very unhappy up, but it doesn’t sound this is just because of the baby, sounds like it’s being going on for years.
What help did you get her re the fake blood/od issues? Did she attend any type is counselling? Could she go back to this?

Presumably you came from a position of secure attachment? It sounds like by the age of 11 this girl had had three parenting set ups? A mum who she doesn’t see anymore, a grandma who doesn’t want her (why didn’t dad have her straight away - so he was probably forced to have her) and a dad and step mum who have had another baby so they’re probably going to give up on her soon too.

There are special things in the house she’s not allowed to touch, her own space is being used because of the baby so she’s being pushed out, people don’t even speak to her unless she speak first.

The lies and attention seeking can be really typical for these challenges, this is the only way I can feel validated and like someone is interested.

I don’t think you understand how what she has experienced has impacted on her

yes I got her counselling through the school. She laughed about it with me and her teachers and said she only does to get attention!

Sorry, misread the OP in terms of age

comments on drawers and blender still stands though - great way to make her feel less important than the baby when she must already feel very insecure

TheLarkAscendingRose · 17/08/2025 09:41

I feel sorry for her because you're the third different mum she's had. Her bio mum who disappeared when she was 8 , then lived with your dh's mum, now you. She was probably worried she'll be pushed out by you having a bio dc.

Overtheway · 17/08/2025 09:43

It sounds like she has some pretty high support needs to be honest. Why doesn't she see her mum and why did she live with her grandmother instead of one of her parents for part of her childhood?

Has she had therapy to work through these issues (there is no scenario where not seeing her mum isn't a trauma, even if it's in her best interests). And did she have therapy for the subsequent lying, stealing, self harming? As you said, this goes beyond 'normal' teenage behaviour and suggests something serious may be going on in the background.

A new half sibling can be incredibly difficult for any child and it's easy to see how this could exacerbate her behaviour, but it seems like she was troubled long before you chose to have your son. Her dad (and you, if you have taken on a parental role) really need to unpack exactly what's going on in order to support her and have a better home environment for all the family.

Starlight7080 · 17/08/2025 09:44

She obviously needed counselling when she was younger. Not having her mum around and living with a grandparent just makes a child feel rejected. No matter why it happened.
The acting out in school for attention really highlights she was not coping mentally.

She needed serious help at that point.
I would see if she would be willing to go to therapy now.
But also a lot of the behaviour now like rolling eyes or being a bit rude is very normal teenager phase.
Having a blender just for a baby is weird .

A) school counselling is notoriously pants for this type of issue. She needs a specialist
B) she is doing it for attention is a clumsy and dismissive way of saying she is seeking validation and for her difficult feelings to be heard. Ignoring someone doing this just compounds the issue, you need strong boundaries and consistency but you also need to be there for her and hear what she is struggling with.
