Thank you for all of your responses.
I absolutely agree with those that have said that it's wrong to exclude a child.
However as a mother, repeating this child's behaviour to mine in my head, I don't want to hand him a treat.
To those that are concerned about whether the gift bags are allowed at the moment, yes they are.
They are given out by the birthday child or the parent at the end of the school day, in the playground as the children are leaving. So it's nothing to do with the staff.
To those who think a 9 year old is too young to know better, this 9 year old swears in the playground on a daily basis, however knows not to speak like that in the teachers presence.
All acts of aggression from this child have been carried out when the teacher has been conveniently not in the vicinity.
And to those that are choosing to ignore the racism part, I can surmise that are from a point of privilege where you have never been racially abused.
Bullying or having said something nasty to you is on a completely different level to being abused for your skin color.
For those who are asking how my DS would feel if he were to be excluded, how would your DC feel if someone told them that they don't belong and need to go to a Muslim school? I mean since when does being brown skinned automatically mean you are a Muslim?
Regardless of all of the above, I have decided to wait until restrictions are lifted to give DS a little birthday party with his close friends.
