DD started reception in September. She's a young starter, she was 4 in July. Just before half term her class teacher & TA told me that DD is essentially not talking in class - not to the teachers nor her classmates. I went for a stay & play there today so saw first-hand, she didn't talk to anyone while I was there, and only one word to me
.
She often is reserved in new situations and with new people, until she gets to know them properly, but I'm starting to worry that in a full class of 30, she doesn't really have the opportunity to get to know the other children in the way she would normally, and doesn't get nearly enough attention from the teacher/TA (understandably).
At home she is talkative, fun, runs around with her younger brother; she is also this way at the childminder's after school and has made friends easily there - so I know this is her 'normal'.
I've tried a few playdates with some children from school, but it doesn't seem to be translating into proper friendships back in the classroom.
I've talked to her a bit about how important it is to talk to people, so they know how fantastic she is, how clever she is etc.
It breaks my heart to think she's there each and every day not really talking to anyone, not really having fun, not engaging. 
Any ideas for how to encourage the talking?
