DD is only just 4 so one of the youngest in her class of 30. Whilst very happy at school, I have noticed she appears less confident and bubbly than when she was at a private nursery in a more intimate setting. Teacher has confirmed she never raises her hand to answer even when she does know it. She has cried inconsolably at home a couple of times when we have laughed at her for getting something wrong. Obviously we were laughing at the cuteness of the mistake and not at her but she didn't realise that. I'm just worried she's going to withdraw further and perhaps not even try for fear of getting things wrong. I'm not sure how to deal with this. I do give her very basic stuff to do and praise her massively for her efforts but apart from that, how can I make sure she knows that it's okay to get things wrong? Is there a book for children that young? Thank you.
