Families with handicapped children--who helps whom and how?

So much has been written about handicapped children and their families that one hesitates to add to this, but, equally, relatively little seems to have been discussed about all the various professions who are together concerned with helping these children and their families and how this can best be achieved. Secondly, it seems even more important that the caring professions should be aware of what these families feel about "the help" which they are given--only by knowing this can we all learn how to work more effectively together.
