Please Help! My 6 year old's behaviour has taken a dramatic turn....

First time poster. Looking for genuine advice from any parents who have encountered a similar situation please....
As title states, our 6 year old DS's behaviour has effectively changed, overnight in a dramatically shocking way. Background and history - at school he is a bright and happy boy seems to love it and meeting expectations for his age so all good there. BUT his behaviour has been flagged to us by teachers in recent times for distracting people at school and sometimes arguing in the playground (poss emotional dysregulation). We had noticed this a little bit at home - but it was nothing beyond what we believed you would expect of a 6 year old boy. Also background, 8 months ago we welcomed a new sibling into the family, making him a big brother.
Cut to these current Christmas holidays. In the last two weeks DS has become a COMPLETELY different child, behaviour wise and mood wise. He can be totally normal and articulate, engaged and happy one minute, then the next minute with no real trigger to speak of, he flips and has a major mood swing that involves hitting us, screaming in our faces, digging his nails in until we bleed and spitting in our faces, saying he hates us and damaging things in the house purposefully - this is all elevated behaviour, something we have not seen from him on this scale ever before. These situations last anything from 5 minutes up to 90 minutes and it can take ages for him to calm down. To give some examples in just the last week alone : Daddy was tidying up the kitchen and put Christmas present money in an envelope that was his, so it didn't get lost....he hated the fact his money was touched and threw keys at Dad's head. Yesterday, he lost the soap in the bath and got so angry about it that he poured water out of the bath, threw it up the walls and flooded the place until everything was dripping, it was unreal. Tonight I don't know what the trigger was at all, but he was furious after dinner and basically hit me at bath time, purposefully wee'd on the floor instead of the toilet, screamed and spat in my face then proceeded to trash his bedroom - took about 1 hour to calm down. After all these instances, he will eventually calm down and say with remorse 'I'm really sorry Mummy that I hit you...and I threw X at you' etc so he seems to sit with it for a while, then apologise. After he's calm, he riverts bac to his normal happy self and you would never now anything bad has happened. Best way I can describe it is...a real Jeyll and Hyde moment.
What am I asking for? I am wondering if you have encountered similar behaviour, which feels like it has come out of the blue. I can't stress the out of the blue bit enough. He's SO incredibly hard to manage right now and I'm really worried about returning to school as he has become so different in these holidays. I keep racking my brains as to what this SUDDEN CHANGE could be... could it new sibling related? could it be ODD? We are currently in the early stages of investigating with a doctor to see if he has ADHD due to school concerns, but his behaviour has changed so dramatically since we saw the doctor about poss ADHD (only 5 weeks ago) this new behaviour feels like more of an immediate issue. He is being violent towards us but not his baby sibling at this point. He is not self harming but keeps saying we don't like him, which is new. We are a really loving family so this language is also a shock and makes me really sad. We've tried punishment, ie. 'don't throw that please else I wont take you X' and followed that through which cues more anger. We've warned and said we will have to remove favourite toy and done that....we've also shouted. We've also tried the calm approach, none of these work. He is the only one who can calm himself down when he is ready. We really need to get his behaviour under control immediately and get to the route of the issue. Is this behaviour familiar to anyone?

Would appreciate any helpful thoughts...... Thank you!

@Sophieishilarious actually one thing that I did do was try and have 1:1 conversations about him to eke out what was bothering him (with the assumption that he probably wouldn't consciously know or articulate it). We did have a chat one day and I said "it's hard being a big brother isn't it, it can feel like mummy and daddy are always giving all the attention to the new baby", which seemed to resonate with him as he then spoke about how he wants to be with mummy but mummy is always focusing on the baby etc. It wasn't a silver bullet but think it may have helped him work through his feelings, and it also gave us an opportunity to talk about potential solutions (e.g. agreeing that if he wants attention he will say mummy I need you rather than screaming and hitting)

Take him to the GP with a list of things he has been doing.

@Skybluepinky did this already, wasn't fruitful. Had to go private.

@koalabearboombox yes you are right there is no silver bullet and it really is so tricky because even at 6 children find it very hard to articulate how they are truly feeling. I have a friend who has a 9 year old who similarly can't articulate how he is feeling. We will get there.....!

@Covidwoes thank you for this. I had read about this because another poster on the thread brought this up. I did mention it to the doctor this week who proceeded to dismiss it saying there is no evidence for that.... I've read up on PANDAS and I understand and believe it's possible though.

Be aware that U.K. NHS has not caught up with this. GPs have no training about it.

I am not an expert. But yes this is familiar . DD1 was like this at this age, she has a neuro condition which affects her emotional regulation and also makes her more tired.

I wonder if this is the combined effect of DS having some kind of neurodiversity (maybe ADHD, maybe something else) plus school getting harder and more rigid (much less play based) plus new baby sibling (lots of impacts on him) plus winter term is exhausting anyway. He just can’t hold it in any more and it’s come out at home. Coke bottle effect.

Consequences, bribes, reward charts etc will not work as he is not able to make any kind of decision about his behaviour “in the moment”. What helps is watch him carefully and avoid getting to that switch flipping moment in the first place. Tiredness, hunger, a cold coming on, perceived criticism or too many demands at once, these are things that will make his switch flip. So try to avoid those. And if he does flip, don’t lay in with consequences or telling off - that just restarts the cycle. He needs to calm himself down as you say, so make sure he is safe, delicate items are removed (we did have a few rage breakages but thankfully mostly things like pencils) and stay quiet. Easier said than done I know!! Then you can have a conversation about it another time, when he is calm - but make it a “ok here’s what you should do instead when you feel like that” rather than “omg that was awful”. In DD’s case things got a lot better as she got older although she’s still a lot more volatile than the average!

Also early nights, plenty of food incl (healthy) snacks between meals. DD could cope with something going wrong/being told to do something , or being hungry, or tired but she absolutely couldn’t cope with 2 out of those at once.

How’s his sleep?

@minipie I just want to say thanks so much for your input with your comment. This week alone I've been watching for potential triggers that might set him off and I've stayed really calm numerous times (I have not succeeded with this very well before) and if he has kicked off it has not been for long and have been able to de-escalate. Thank you again.
