DS had two boys with significant SEN needs in his class at primary.
When kids had a full class party, one was well looked after by his Mum but the other was unmanageable and even when Mum was there she was known for not intervening.
I remember three particular parties - one where I ended up managing behaviour because none of the other parents did and half the kids were getting upset (and harm), one when I'd refused to go due to previous above mentioned party and DH went instead and he ended up telling the kids to get down off the tables at one point and a third party when this particular kid was about to throw a chair, and me and another parent stopped him, it even though Mum was stood right next to us at the time. She was too busy drinking her glass of wine.
My point here being, that parents are not trained to deal with SEN kids. If the parent of the SEN kid isn't prepared to manage their own child's behaviour then that's ultimately a parenting problem. I know my limitations.
I don't ever regard myself as excluding the kid. I was unable to make suitable reasonable adjustments.
More than that it was the parents attitude that I had issues with and it was their problem to fix not mine to enable. They did not want to accept their child was SEN and just said he'd grow out of it and it was just because he was one of the youngest in the class.
These parties were always too much for this kid. He couldn't cope with them. They couldn't be arsed with dealing with him. There was one particular occasion where he said to me and another parent that he could do whatever he liked because his Mum never told him off. He knew this age 7.
In the end DS never had a full class party because of this child. We just had a small group of friends instead. I also refused permission for DS to either have or go on a play date with this particular kid. There were too many other parents who had done so and then ended up with massive issues. It wasn't safe or suitable as an environment for this kid or mine.
No one could reasonably adjust to manage the situation because the parents didn't want to deal with it or admit their child's behaviour was unacceptable. If they had been involved and trying I may well have taken a different attitude. I was never willing to take responsibility for the violence myself. I had to go to school on numerous occasions about safeguarding from this child and knew it was happening to other children too. Why on earth would I want to be 'inclusive' of them? A small number of the other children would actively self exclude if they knew this kid was going to a party. I know because we stopped DS from going to one or two parties because we knew how it would go. We weren't alone. It was the Little Johnny Show and we didn't want our kids to have supporting roles or become casualties of him.
The other kid in DS class with significant SEN needs was lovely. The parents were lovely. He sometimes did go boom. But because it was dealt with and supported properly without denial and abdication of responsibility by parents, we never had issues. Indeed DS invited him to his small parties and is still in touch with him regularly even though they are now at different schools. The difference was enormous.
It is rarely merely a SEN issue. There's SEN issues and involved parents who will start, help, intervene and manage a situation at a party if it arises. And there's SEN issues and parents who do fuck all but drop and run as quickly as possible or worse stand there and watch and then wonder why their child isnt being invited to the next party. Parents with SEN kids who genuinely can't cope in these situations, don't want to put their child in that situation because it's not good for their child. Or they know the limitations and have an active plan to cope and minimise issues for the well-being of their own child.
This child in DSs class was ALWAYS invited at nursery and in reception. Over the years the other parents get wise to the dynamics of kid AND parents. The kids themselves also get wise to it through experience. They wanted their party to be good without the drama and someone else taking over.
Running to the school and telling on other parents is hilarious in this context. Why aren't you managing and parenting my child's social life outside school as well as parenting my child in school?!
Parents should always have the right to say no, because in their heads they are writing a risk assessment about the situation and saying no this doesn't work and we don't have the skills to manage it not the ability to make reasonable adjustments. It's not exclusion. Its safeguarding all the other kids. Which frankly often isn't happening in schools when it should and this is creating unreasonable expectations outside schools for other parents too.
