Because early intervention holds the key in making substantial improvements in autistic children, there is no time to waste if you suspect developmental delay. The first action is to acquire a medical professional who is experienced and who can guide care as soon as possible. Sometimes this can be quite delayed.

These may come from non-medical sources at times, but always support groups and web resources provide valuable sounding boards for validity.
