回复：自闭症(Autism)

for kids at young age, one of the best approach would be
ABA therapy,

you can get the book from Amazon, the book name is
let me hear your voice

the same author has another book for ABA therapy program
this is a proven effective therapy

it is a very involved program. some states fund it with early intervention fund, some insurance covered that too. but in most of places is not covered.

paying out of pocket for ABA is very tough. it is so expensive. but you can learn it and do it by yourself.

Search a bit more. Autismspeaks.org is a good resource.

good luck
