My daughter is very shy and typically quiet in class but she does have a couple of friends, including a girl called Laura. When Laura is at school my child is interested in what's going on and engages with others, but when she is absent my child becomes moody, unresponsive, and doesn't do her work. It's like my daughter is dependent on her. Their teacher has spoken to me because it's become something of a problem. I feel like she might have a social problem, but maybe she's just shy? Does anyone have a similar experience with a child?
