My dd is almost 6 and likes to do well at school. We are never critical or chastising when she gets things wrong etc, nor do we encourage her to be over competetive.
Tonight she has had the mother of all meltdowns about a picture of her face she did at school which she is hugely upset about as it is, in her words, "rubbish". Her teacher said it was good, but she is utterly convinced its awful. She cried for an hour and I had to sit with her while she went to sleep to keep her calm.
She has had a tiring exciting week and had a friend round for tea earlier just to add to the excitement! Could it just be tiredness/over excitement? Surely she is too young to become self critical yet???
