Which supplement/treatment helps most with increasing phrase length.

[Guest guest]

In your opinion, which supplement/treatment has helped your child the most to

increase his/her phrase/sentence length. My 5 year old can say all of his sounds

in isolation and uses 3 word phrases that are a little hard to understand to

some people, but anymore words than that at once are a garbled mess. He also has

autism and didn't begin to speak again until he was 3. (after stopping at 15

months) So if you had to chose one that you believe did the most for your

child's language, which would it be?
