My ds is 5 and in year 1. He moved schools at the end of Reception and so far, seems to have settled very well into the new school. However yesterday, he came out of school very upset saying that since he'd been off sick (last week straight after half term for two days) nobody will play with him and the group he had been playing with was now deliberately leaving him out.
I went through the usual "try and find someone else" conversation (he did say he'd tried with no success ) but talking to a friend of mine later, she said she would definitely approach the teacher and suggest she had an "inclusiveness" type chat with the whole class.
TBH this hadn't even occurred to me, as I tend not to see the teacher about anything much as I don't want to take up their time whereas my friend is quite forthright about fighting her children's corner. Just wondered what the wise world of MN thought - what would you do?
