My DD (5) can be very fragile in situations where attention is focused on her. During dentist/GP appointments she will scream and hide under furniture, attempts to run out of the room, attacks whoever is trying to calm her down etc. She's been much the same when making her Rainbow promise or doing nursery sports days. However, she had no trouble doing school nativity or her class assembly - it seems fairly unpredictable but is extreme when it happens.
I was warned by her TA that she is refusing to practice for Sports Day and is starting to get wound up by the idea. Could I build her up and tell her it's not about winning. Well yes, I could... I've already sat her and DS down and promised them all manner of reward if they can just start and finish their races without crying
but it's not making an impression. Tbh when she's in one of these moods, nothing gets through 
I can't take her out of school because I want to watch DS. The TA said she wouldn't be allowed to sit it out with me.
WWYD?
