Stepchildren stealing and lying

199 replies

GirlMama99 · 24/05/2025 08:19

Short backstory - married for 6 years to husband who has 4 kids from previous relationship. BM not been involved at all for 7 years. Me and DH have 2 kids together (2 and newborn). His children have always had problems with stealing, lying and sneaky behaviour since as long as he can remember apparently.

His son who is 13 has been caught stealing money from his grandma's purse, his dads wallet and from my hidden away saving jar. He also steals our phone chargers and other random things he takes any interest in. He's broken several of my babies toys, every phone or tv we have bought him has lasted weeks before being broken. He never showers or brushes his teeth without being threatened to take privileges away. He lies about completing his chores.
He is becoming a teen and I'm at wits end. I don't feel I have a right to discipline as I'm step mom and don't want him to hate me but I would not allow this from my bio kids.

I had my newborn last month prematurely (long hospital stay and me having health problems since, in and out of hospital). A couple of days ago I felt up to trying to cook a roast lunch for me and my toddler whilst the other kids were at school. It took me 4 hours to cook this dinner between breastfeeding and a screaming toddler running around. I had leftovers in the fridge which were going to be mine and my toddlers lunch the following day. When SS got home from school he instantly scouted the kitchen as he does and found my leftovers. He asked who they belonged to and I told him. The next morning he had eaten my leftovers. DH told him off (which does nothing) and said he was having his phone confiscated for a long time. The next day he has his phone back.

I am so angry about this because I feel extremely disrespected by both of them. This isn't the example I want set for my kids and I'm sick of these issues constantly in my house.

DH and I aren't speaking now and he's told me he and only he will discipline his kids how he sees fit and it's not my business.

It's awful. People are so desperate to jump in with their withering little put-downs. OP has explained multiple times and yet people just won't fucking stop!

Yes, the self-righteous do love to prowl on here. It's all projection and they think it makes them feel better but it just masks their own insecurities and less than perfect lives.

This with bells on. It is hereditary. You may well find that your 2 children are also autistic.

As a mother of an autistic child - this sounds like an absolute nightmare.

It wasn't cooked for them because they never eat it. It gets chucked away and it's expensive and time consuming. That's why we did them chilli. I also couldn't afford more than a small joint as DH is not working whilst I'm having ongoing health issues and we are broke. Another reason why the leftovers were important to be for mine and daughters lunch the next day. Like I said, they get hot meals at school and leftover money from bus fare to get snacks after school on way home. It is stealing because he was point blank explained what the food was for and his was there. The charger is an ongoing issue. He has broken and lost so many chargers , he had no intention of giving it back he even lied about where it was. He had taken it out of the wall socket with my baby monitor plugged in, that's how i keep my daughter safe to be in another room when I'm breastfeeding.

If you’re the one with health issues then why isn’t your husband working??

He has six children to support.

Every household has their rules I guess, but when I was a child certain food were available to eat freely (fruit, crudites, bread, soft drinks, yoghurts, etc) but for the rest we were expected to ask an adult, not just help ourselves!
Same goes for my DC today.

That still wouldn't be stealing. What else could they steal 🤔 water, warmth, electricity?

Lizziespring · 25/05/2025 19:02

You're not being unreasonable and neither are the children.
Stealing can be a sign of trying to fill a hollow or replace loss. Lying can be a sign of fearfulness or being at bay.
Maybe 13 seems old when there are tiny children around too, but it's not. The surge of hormones feel like being a big toddler emotionally.
Maybe a youth counsellor or even just youth club might help?

DoubleMM · 25/05/2025 19:07

Good grief- they are children. You are supposed to be the adult. You made a roast dinner for you and your toddler(wtf?) and put the “leftovers” in the fridge and you are angry that the older boy ate them? Are you that selfish greedy and withholding with all of them? Their mother has “gone” and you have pitchef up in their lives making roast dinners(again wtf) for yourself and calling it stealing when they eat your leftovers. And you call them monsters? No wonder they are unhappy and “stealing” things because they are not loved

RubyTuesdayFTO · 25/05/2025 19:31

Stealing and lying is a classic sign of childhood trauma and attachment insecurity. You say their BM hasn’t been on the scene for 7 years? Bingo there’s your answer. It’s a very complex situation but this is a result of unmet need (not in the way you think) Please look into therapeutic parenting groups on Facebook. It’ll break your heart when you realise what’s actually going on (step mum here also).

Init4thecatz · 25/05/2025 20:17

This is why the negatives of being with someone with kids FAR outweigh the positives.

If they're awesome and you love them, if the relationship ends, you have zero rights to them. If they're sh!ts and you hate them, you can't get rid if them, and you have no power to discipline them.

Your partner clearly has an 'us against the world' mentality... you're just tagged on, not an actual partner.

MyOliveHelper · 24/05/2025 08:36

I find it weird that you'd cook a roast that took 4 hours for just you and your toddler and the other kids wound have to raid the fridge for food. Why isnt there a proper meal prepared for all children?

Yeah they sound wild, but the set up sounds weird.

I agree with this—I can’t understand this food pattern. One of the step children takes food out if the bin? That is a sign of either disordered eating or disordered parenting. My money is on extremely disordered parenting.

Sorry: I have just seen the information on the ASD child. I still think there is really problematic parenting here but that ship has sailed given that OP’s DH chose to have two more children when he couldn’t handle the four he already had.

If your husband isn't working why couldn't he have helped you make lunch instead of you having to run backwards and forwards breast feeding when you have so many health problems?

Theroadnottravelled · 25/05/2025 21:02

This is batshit. I’ve read the whole thread and feel for the OP but it seems like a ‘no winners’ situation whichever way it pans out. The DH must be amazing in bed/very charming to get anyone to agree to two more children on top of the four he already had with no mother in the picture. I’d have run a mile. But the ship has sailed. I’d advise leaving, it won’t get better and there are 8 people to consider in this messy family muddle.

caringcarer · 25/05/2025 21:15

Why didn't you cook a roast dinner for all DC? Also you mention his kids scouting the kitchen for food after school and another eating food from the bins. It seems to me these step kids are hungry and need a reliable food source. They wouldn't need to steal food then.

theonlygirl · 25/05/2025 21:19

You've given 6 years of your life to this man and his children but something isn't working. If you can't come up with a joint plan on how best to parent all the children together, meeting all their needs you need help from outside agencies. Or you need to seriously think about separating your households so you can focus on the younger two and he can parent his four children the way he sees fit.

GiveDogBone · 25/05/2025 21:44

Any step parent has the right to discipline their step children when they’re under the same roof. Or to put another way: my house, my rules.

This needs addressing immediately, as you say your younger children will be copying the behaviour. Frankly, unless you want them to end up the same way you need to remove them from the situation urgently.

Why didn't you read OP's MANY posts explaining that the roast was for two lunches for her and her toddler and the other kids favourite meal of a big bowl of chilli was waiting for them when they got home from school?

The way this thread has become all about why OP made a small roast for a lunch that the older kids weren't present for, rather than the issue about the DH's refusal to let her parent, is just insane.

anon4net · 25/05/2025 21:55

Chronic theft is almost always indicative of a much bigger problem. Their bm has clearly abandoned them so there's trauma there. They could also have other neurological things that make impulsivity much worse (FASD, ADHD etc.). Childhood trauma alone is highly correlated with both theft and lying. You also can't discipline trauma away, which may also be why discipline isn't working.

I do not say this as an excuse but I'd be curious as to whether they've had support around their mother leaving, their relationship with her and anything else.

I think you need a good conversation with your partner, an effort to be a team and a bit of a reality of what needs to happen to make your family work - for you, for your children and for your stepchildren. This will only become a bigger issue if the right supports aren't found and/or you carry on as you are.

GirlMama99 · 24/05/2025 08:38

Thank you for this. Yes I do cook for them, clean up after them, buy them clothes, book trips, all the usual parent stuff. But DH tells me I don't have to do these things so therefore I don't have a right. When I say "but I do parent them so I do have a right, he says don't parent them then". I feel like his disrespect for me is seeping through to them. I have been miserable living together since the day we did it. But feel so guilty to rip the family apart and leave especially since they don't have a mom involved.

Maybe there's no mum involved because he's such a plonker.
Maybe he's stepped back on the discipline because he now has you there so he can sit back and relax while u bring up his kids and Ur own.
Id not be putting up with this because it doesn't work for you or your kids at all. He just has got lazy and wants to ignore Ur wants/needs now you are in.
Time to have a talk and a plan to leave which you will carry out unless he starts working hard with you to turn this disaster round.

GreenTraybake · 25/05/2025 22:50

Re:Roast dinner, it is actually more sensible to meal prep instead of cooking lunch everyday so no problem there. Important questions;

  1. Does child with severe needs go on the bus alone as well after school?
  2. DP is not working, why does he not help with the little ones or help cook the lunches for you?
  3. Have you met their mum? Why did she completely disapper for 7 years?
  4. Seeing as everyone is out of work, what are the plans going forward? 5)Have you guys considered counselling for everyone especaillly the kids who seem to have obviously been affected by the divorce and mother completely running away from them?

We all sympathise with you OP but there are so many questions here and unfortunately, it would be hard to give any advise based on the drip feeding and scarce facts

HoskinsChoice · 24/05/2025 08:29

Why on earth did you bring 2 new children into this household when the first 4 are running wild with zero discipline? (Probs a bit late to say that!)

If there is no BM on the scene, you ARE the parent and need to parent. If he won't let you then time to move out so your own kids don't go the same way.

This exactly. What a mess and recipe for disaster. I wish people would focus on their existing kids first.

Purplecatshopaholic · 24/05/2025 08:38

You married a man with four kids, thought having more kids with him was a good idea, and didn’t see this was a disaster waiting to happen? Ok. You have made your bed here and all those kids need parenting. The first four dont have their mum around, only you - parenting and discipline is part of the deal. Your DH and you need to work as a better team before they all go off the rails one by one. You two need a serious talk about how you both are going to handle the parenting going forward. He can’t just throw his hands up, he has to take responsibility too. If he won’t, sadly you may need to consider leaving for the sake of your own kids.

Edited

Absolutely. Poor kids honestly.

Nextweektoo · 25/05/2025 23:09

You say these are not new behaviours, so you basically knew all this, as well as agreed not parent these kids before marrying him(and having 2 more children, what were you expecting to happen??

Matchalattetime · 25/05/2025 23:13

arcticpandas · 24/05/2025 10:51

So you moved in with a man who had 4 children and one of them being severely disabled. Their mother not being in the picture. And you have two more children with him. He saw you coming.

This is it. Men like this who are parenting alone and aren’t coping with their current bunch of kids, will go on have the additional children with a new woman so they will stick around and raise all of them.

A man with four kids once approached me and I practically laughed in his face and told him why. He said it was rewarding to look after other people’s kid - I said that’s nice you feel that way, go find a single mother to help out! He went silent at that one - go figure.

It’s wild to me that men say women are too fussy, when there’s women who will take on a man who has 4 kids with various issues and actually have more children with him.

ChocolateIsForLife · 25/05/2025 23:19

You say you’ve been married for 6 years so how long have you been together?
Did you get married after moving in?

Laurmolonlabe · 25/05/2025 23:42

If discipline is not you business then the kitchen and fridge is out of bounds to SS. Tell your DH the next time your money goes missing you are reporting it to the police- my brother was like this ,and my mum enabled him as your DH is. He very nearly went to prison when he left home-the outside world weren't indulgent like my mother.

TwinklySquid · 26/05/2025 09:05

Some people are focusing on the food. It’s not about the food.

This sounds like a nightmare. I would look at trying to leave this situation as it doesn’t sound like you are getting much out of this relationship.
