Hello. Dd is doing her first solo violin performance in the school carol service this week and having been note perfect for weeks is now forgetting the notes, squeaking and catching the wrong strings. She's got in a right state tonight sobbing and saying she's going to get it wrong etc. Everything I say is wrong. If i say it will be fine she points out all the things she got wrong tonight. If i say no one will mind if she goes wrong then i think she will get it wrong too. Any ideas how best to deal with this ?
