Recent feedback for the Intermediate Course from an experienced social worker

I am seeing how without the right training or understanding it is easy as a carer or professional working with a complex child to start to feel very negative feelings. I used to work in residential care however I had no training, it left me feeling emotionally drained, stressed, like a failure. Sometimes my responses won't have been great.  I can now see that for parents who have other stresses in their lives it is easy to start responding to negative behaviour in an equally negative way which then becomes a cycle. My current concern is that many parents or professional carers are clearly still not getting the training they need to be able to manage their own feelings and responses when caring for children or adults with complex needs.
