They shouldn’t be excluded just because it’s an inconvenience to take them. If there are staff to stay behind with them, there are staff to go with them and act as a one to one
^^
Except as the OP says, the nursery's expectation was for her son to stay home. Because they clearly didn't have the staff to stay.
At nursery there is rarely funding available for one to one. DS has just been going through the initial phase of being assessed for ADHD and they don't start doing that until a child reaches age 6. So that creates 3 - 4 years where there's a potential problem for a certain % of kids. That has massive implications.
There was a child at my son's nursery who was unmanageable. He had to have a one to one on a nursery trip. I helped out on it and I remember him getting away from his one to one who he was supposed to be holding hands with, in a fenced playground. It resulted in a massive standoff and him shouting abuse and chasing episode before she eventually managed to get hold of him. It was not nice to watch and had it happened in another area on the trip it would have been dangerous. The nursery assistant was amazing and very experienced but it was still a level beyond what was reasonable. He was 3 at the time.
He's still in my son's class and there's still massive issues ongoing. School refused to take him on a number of trips in reception and yr1. I think yr2 was the first time he was allowed to.
At Christmas this year the class went to do an event and mum was told he would not be going unless she took him directly to the venue and back. They were really short on volunteers for that trip. I ended up walking backwards and forward 6 times that day because no other parent volunteered and without me they would have been below minimum numbers. They certainly couldnt have coped with this kid.
We are now in yr3. This kid STILL hasn't got a 1 to 1 as there isn't the funding available without him completing an assessment. Mum and Dad refused to allow it for several years and it's only been with a number of increasingly violent and disruptive incidents that the school has been able to push it (I think they basically said if they didn't agree to it, they would refer to social services to force the issue). So hopefully we are now starting to get somewhere
It would be nice to think he will have a one to one by September, but honestly I'm not holding out hope. I suspect in a best case scenario we are probably looking at yr5. COVID has massively delayed where we'd likely be otherwise tbh.
What's been fascinating to see throughout is mum and dad minimise the behaviour and still think his behaviour is normal and he's just a boisterous boy. And because nursery and school aren't allowed to say negative things about a child they've had to go round the houses using euphemisms for his behaviour rather than directly saying stuff especially as mum is incredibly over sensitive and has felt he child has been treated unfairly (he hasn't - the amount of accomodation he's been given often at the expense of others has actually been outrageous). She's pushed back at everything and has had head firmly in the sand as part of her denial. It's not helped by the extent to which her son lies and is deceptive.
The whole thing is a right mess and it's not nice. He needs the support but his parents have actively been a barrier in that. Ultimately we have had to make a massive fuss this year and stick our necks out where others haven't. Because no one wants to upset mum 'because she's so lovely' and everyone has spent years tripping over themselves being nice and polite not wanting to upset or rock the boat. (Whilst quietly moaning out of her earshot). We view it as he needs help and he's never going to get it, without other parents forcing the issue.
Due to my experience of this, I'm now incredibly dubious who say these things come out of the blue. I've spoken to her directly about stuff and it was only after multiple incidents where we had to involve school that she started to take it seriously. Even then she acted and spoke as if it was a shock when it was escalated and had somehow come out of nowhere. It staggered both me and several other parents just how unaware of the issues her son has.
I am doing my best to steer well clear of her rather than get into uncomfortable conversation which will inevitably occur otherwise.
But yes, saying 'oh just get a one to one' or 'just make sure they hold hands' is grossly naive and ignorant of how some kids behave and the resources available to help them. You simply haven't dealt with kids like this and how difficult they are to manage, and how little support is actually available.
OP don't be this Mum. Get on top of it. If this school manages your son out, then deal with it as a positive rather than trying to go into battle. They won't be the right place for your son if this is the case. You need good communication and proper support. Head burying helps noone least of all your son.
