To not be happy with this response from nursery

[mummaoftwo22]

DS who is 3 started school nursery last week, today was the first full day he has done.
He has settled amazingly and has been excited to go back this week. I picked him up this afternoon and when we got home and I handed him a drink I noticed a bite mark on his hand, nothing was mentioned by staff at collection in fact there is basically no handover at all, I just sign him out and off we go.
I spoke to DS and when I asked him what happened he said a girl hurt him but he wasn't upset, it's bruised and grazed from the teeth so I'm not sure he wouldn't have been upset.
I called nursery to see if maybe a form had been missed at collection etc and they called back to say that there were no forms and nobody had seen anything happen to him at any point so "sorry about that" and told me to make sure he knows to tell an adult if it happens again. Aibu to think they should be keeping a closer eye? DS is a very good talker so is usually able to communicate(albeit not this time) but they have 2 year olds that I can imagine aren't as good at communicating yet.
I get it these things happen they are still only little but I don't want this becoming a regular thing and it putting DS off going when he's been great so far.

*It’s unfortunate but unavoidable that these little things sometimes happen.

I think the response could have been a bit better though. If it was me at work I’d have apologised that we didn’t notice and let them know we would keep a close eye to make sure it wasn’t a pattern of one child biting/would talk to all the children about telling a teacher if you are hurt by anyone etc*

I agree with this.

You said it's grazed - did it break the skin? If so, he might need antibiotics due to all the germs in the human mouth (NICE guidelines -www.nice.org.uk/guidance/ng184/chapter/Recommendations#antibiotic-prophylaxis-for-uninfected-bite)

Thanks everyone, I'm not kicking off at all I understand completely that these things happen, it was just a bit of a shock to see a big bruise. Unfortunately DS doesn't know many of the children's names yet as he's only been there for 3 days and I'm assuming the children do different sessions so I can't let staff know who it may have been, we have been talking tonight though about speaking up if anyone hurts him so hopefully once he's got his confidence he will. I will let it go this time and just keep a close eye.

@Creameggs223 we are in Scotland so I'm not sure if it's different elsewhere but we have a thing called 'eligible twos' where two year olds of parents on certain benefits qualify for 30 hours a week of local authority nursery, so there will definitely be some in there.
