Dear Concerned Grandmother:
Autism is a very difficult diagnosis to establish because of the age of a child. Most pediatricians will do an M-CHAT (Modified Checklist for Autism in Toddlers) at 18 months of age.
If it reveals areas of concern, a full developmental assessment is recommended but what most of us know today is that many in the medical industry do not follow through with patients -- so it will be up to the parents and other relatives, like yourself, to make sure your grandson get what he needs.
Make it a point to visit the pediatrician with your daughter on the next doctor's visit and bring up any questions you might have. Early detection and early treatment will be the key for your grandchild to develop correctly so again stay involved with this issue. You should be commended as a grandmother.
