DD1 is almost 7 and is mostly a lovely, lively, chatty, confident child. But she never seems to think of others or their feelings. I am not sure if this is a natural/personality thing or I have done something very wrong.
Today there was a perfect example: DD2 burst her balloon and DD1's first comment: 'Well at least I still have mine.' No thought at all for how upset her sister might be. I have tried so many things demonstrating through example, reading stories (shirley huges is good for these) or saying what would have been a nice/unselfish response but to no avail.
Is this normal behaviour for a child of her age and I am expecting too much for her to think of her others? Or am I doing/not doing something I should be?
