Hi,
As Kristen did, we started DS with ABA, OT, and speech at age 2.5, both at home and in therapists offices. DS attended a preschool for kids on the spectrum at age 3, but outgrew it and went to mainstream preschool at age 4. He entered public kindergarten the following year and is now in the gifted 1st grade. Intensive early intervention is the key and while I cannot recommend anyone in Boston, I do recommend focusing on ABA. Most people have no idea DS is on the spectrum and are shocked to hear he was non-verbal til age 3. Of course all our energy and money has been geared toward his therapies, but it has been worth it to see the friendly (and quirky) boy he is! Nan
