So child1 bit child2 ( both age 5/6) hard should kid 1 apologise?

[Rosa]

At a party child opening presents Child 1 wants to see pushes past other children to get closer. Other parents are near and say no don't push to child 1 ( in a nice way like if you all stand back you can all see kind of thing) child 1 then bites hard on arm child 2- who naturally screams. ( there was no pre push shove from child 2 btw)
Parent takes child 2 away to calm down , rub arm etc and child 1 gets taken away by father. Child 1 returns still upset and still crying / shouting . Gets given cake .
Child 2 was not apologised to and parent takes child 2 over to 'make friends' again. Child 1 ignores child 2 and parents make no effort to apologise or speak to child / parent. No eye contact ( 2 parents 1 child )
Talking to the party giver it seems that the child was thought to have an austitic trait - but the parents have decided that this is not true. Whether this is relevant or not I don't know......
However AIBU in thinking this child should have apologised.

Children with asd usually bite as a reaction to a situation they are in not because they are deliberately seeking to be aggressive for the sake of being aggressive. The parents should have apologised but I imagine they are struggling at the moment and some understanding/ compassion should be given. It doesn't sound like they are happy that their son is biting others.

You are so right.

I think that a child who is still het up apologizing is a bit meaningless. I can see why you went over, but maybe it was too soon to expect an apology.

The parents of child2 should have kept the child away until he had calmed down, and not given cake.

The parents should have shown concern for your child and done the apologising at first. I can see why you are annoyed by that.

You mention the possibility of an autistic traits. Maybe the parents are struggling at the moment and are directing their efforts to avoiding public scenes....

I am shocked that anyone would think it is acceptable to take their child to a car and calmly bite them
To teach them that biting is wrong
That's not parenting- that is abuse
And if I did that on my job, I would be sacked

I think it well could be very relevant that the parents don't accept their son might have an autistic trait. They sound like they are struggling to accept him and they're in shock. It could be that they felt there was nothing they could say that would make it better.
It isn't doing their son any favours. I'm not making excuses for the parents, just hoping that they get some much needed help to accept their son, with all his traits.
