Behaviour has changed

[Rosebel]

DS has been at the same nursery since he was 2, he's nearly 4 now. He always loved it in older babies and toddlers. Then he moved to preschool and loved that too.
Until recently.
He started becoming distressed at nursery, then he was bitten which made things worse. Nursery suggested cutting down to 2 days a week which we did.
If anything it's made things worse. He still gets very distressed going to nursery. Yesterday he was shouting at the staff and pinched his key worker (who he normally loves).
I don't know what's going on. He's got autism, is non verbal (so he was shouting but not words just babble) and in a lot of ways his development is in the 8-20 month bracket.
This isn't an excuse for his behaviour but more the reason I can't ask what's wrong because he can't speak.
Nursery think it's just a phase but he's only there another month and I hate the thought of him being upset.
I'm also upset he's pinching the staff and slightly worried he may do that to another child.

If he's only got a month left is there a way he can just leave now?

He's frustrated with something and nursery saying it's just a phrase is bollocks tbh.

Does he have ear defenders and a chew necklace? These have helped my DS massively

He doesn't bite thankfully and won't tolerate ear defenders. I think it's too busy for him. Room has gone from 23 children to 40 in about a month and think it's overwhelming for him.
He's also stopping children from going in to the bathroom standing in the doorway and keeps trying to leave the room every time the door opens.
Unfortunately I don't finish work until July so can't take him out early. I just feel very sad and guilty.

My boy doesn't bite but the chew necklaces gives him the relief he needs when frustrated.

20 is a lot never mind 40.

Do they have a problem quiet spot he can go to when he needs to?

Can you use some strategic sick leave and carer days, plus if you have a partner they do the same to cover this period. You’re entitled to unpaid leave too.

Sounds like you kid is in distress so I’d find a way to avoid as much nursery as possible for this month .

Please take him out. I don’t want to draw too much on my own story but my child was very distressed in early primary school, unable to articulate what was going on, and I got the complete run around from the teachers. Wasn’t until she got older she was able to explain to me how dysfunctional the whole place was
