Oh wow!!! So many answers-thank you!!!
She was 5 last week, and I have the same fear (I find it really hard to hand essays in at uni, as I am scared they aren't good enough!) so know how she is feeling internally, which helps.
At home it took me years to cope with her-you have to go on to an entirely different subject, even if it is mid sentence, and she snaps out of it instantly-it is really weird, and the only way anyone can describe it is Jekyll and Hyde syndrome! Have spoken to the teacher about how I deal with it, and she said she would take the ideas on board (and the nursery nurse has a niece with the same temprement (sp!!), I spoke to her this morning, so has a huge soft spot for dd). I think dd is also a bit worried as her questions are sometimes the kind that you have to go away and find out, so the teacher can answer other people's questions, but not always hers IYSWIM, so think she feels a bit odd.
She does ballet, swimming, and is starting dry slope skiing next week, and she isn't the top in ballet but is in swimming, so gets used as the "show piece", which can't be helping!
If I play tennis/football anything with her, I have always played to her level-maybe I should up it a bit over time so she gets used to not always winning?
