What would the treatment entail? If it was some sort of language therapy, social skills training, OT exercises or providing an educational therapy...I would say sure couldn't hurt as long as it wasn't below his cognitive level and insulting. If it is drugs, no way.

My son was in a birth to age 3 program and an age 3 to 5 preschool program without a firm dx...just a "developmentally delayed" general label. At age 8 we got the ASD dx. Speech, OT, social skills, special preschool did not hurt him...and got him potty trained finally at age 4 and a half.
