To be worried he'll be bitten again

[Rosebel]

Okay hope this makes sense. One of the women I work with has a DD a bit younger than my DS. She invited us and some other people we work with, with similar age children to her DDs birthday party yesterday.
I wasn't too sure about going as DS has additional needs and can get overwhelmed. I spoke to the host and she said it fine if we left early.
Anyway went to the party and another parent from work was there. Her child bites, a lot and unprovoked so I was a bit on edge.
It all went fine and DS was doing really well. I went to the toilet and hear a blood curdling scream and I dash back to see this child's teeth clamped on his arm.
Now we all work in a nursery so I know it happens and I know it happens quickly but honestly I was so angry.
The child's mum did apologise to me and I said don't worry but I'm still cross. DS has a huge bruise on his arm which I will have to explain at nursery tomorrow.
But I feel really angry still and know I'm going to feel arkward around mum tomorrow. To make it worse currently DS and her DD are in different rooms but tomorrow she's doing a settle iin DS's room.
I just don't feel comfortable sending him in
DH can keep him home tomorrow but not long term. I know this child does have certain children she goes for and I'm going to be constantly on edge now.
Shout I talk to nursery? Hope for the best? Just go sick and remove him from nursery?
YABU leave it and stay at nursery
YANBU talk to the nursery and move him if he gets bitten repeatedly

A formal complaint is needed here. What they are saying boils down to that their safeguarding policies only apply as long as they don't affect their ability to retain staff.
That's really appalling. They need an honest conversation with the child's mother about the fact that a group setting does not seem to be the right place for her child. If she leaves, because her child can only be cared for at home and she is the only person who can do it, then that's a shame for her and for the nursery but these are the decisions that parents have to make all the time.

I don't think it will make a difference. I know other parents have complained and nothing gets done.
Is Ofsted a step too far? DH says to do it, but he's still raging especially after the manager saying I should understand.
I'm just upset and keep seeing the bruises on his arm and hand.

I think a formal complaint is in order. They have basically responded to say that they can't do anything and you just need to "understand". Which I think we all agree is not on !

just to give a slightly different perspective.
Mt friend's son is autistic and at 3 was non verbal and started talking at 4. He started at mainstream school with a full time 1:1.
He was a biter. There were several incidents in the playground where he bit, usually because he wanted to play with a toy/bike etc and someone else had it.

My friend went into school and basically said - where is the 1:1 at playtime? All the other kids are becoming scared of my ds because he is biting, but that is only happening because he doesn't have a 1:1. This is not fair on him, and it isn't fair on the other kids who are getting bitten.

School started supervising him more closely, so the biting other kids stopped and gradually he learnt about taking turns and sharing toys etc.

Three, while small, seems quite old for a child to be a prolific biter. Normally it’s a phase that has passed by that age. Does that child have additional needs too?

Yes she is also waiting to be assessed for autism and has limited language too. A lot of her biting is frustration I think but it still doesn't make it okay for her to bite my DS.
