Thanks for suggestions.
There is a Rainbows group after school for dd's age, but it is at capacity. There is talk of setting up another group, but so far it has come to nothing.
School clothes are fine, and the school provides supplies (parents give an agreed allowance for teacher to purchase so everyone has the same thing), so no worries about not being equipped there.
There is a system where you drive to school doors in a loop and staff are waiting to help children out of cars into the building (virtually everyone drives here). It's very efficient, but means no chance to chat and/or get to know the other mums.
There doesn't seem to be a system of class reps here, so no organised coffee mornings. I have volunteered to help out on Book Day, so will presumably meet/get to know some others there, but will be a cross section from the school and not necessarily dd's class.
We've invited quite a few children for playdates (some 2 or 3 times), but return invitations have been sparse. I know it's not because people don't like dd (or me), and not because they're unfriendly - they're all just very busy with established lives. Their time is committed.
DD is signed up to do 2 after school clubs, so that may help her integrate. She is also doing ballet outside school (no classmates attend). We've started going to church, and there are some nice children who are 4 or 5 years older that attend the same school, and dd is always thrilled to see them.
I think I sound very negative, but I simply feel discouraged. I tell myself it will take time, but in the meantime, it's hard.
Oh - will write later about differences in curriculum, which is another area of concern.
