My DD (aged 7) while watching children in need saw a child who was paralysed from the waist down, on oxygen etc at night, a really young girl. DD came out with "shes not a child in need, look at all the stuff shes got". 
On went the programme, my DS (aged 4)was sat crying about a girl being bullied because of her disability, and DD got up, left the room and came back dressed as "lady gaga".
Now this would be midly amusing if it weren't for the fact that she genuinely doesn't appear to care about how anyone else feels. I thought it would get better with age, but it hasn't. She comes across as cold and uncaring, and seems to have no idea of how her actions impact others.
I am really worried that there may be something "wrong", or is it just the way she is?
