Undiagnosed Children's Day Today

This article on Special Needs Jungle Blog talks about the impacts on a family of having a child without a diagnosis.

My son was not given a diagnosis until he was 31/2 and it was so hard to know how best to help him until we got some answers.

Are there any other families out there struggling to get answers?
The charity SWAN- Syndromes Without A Name is a great help to families in this situation.
