Normally around here we talk about inchstones, but in this case, I think it's really time to use the word milestone.
Earlier this week, sitting in the waiting room for the speech therapist, Acorn got out his communication device, and from the main screen, he hit the following buttons:
Quick Talk (a page with lots of sentence starters)
"I want to eat chips"
A whole sentence. By himself.
When I told him we didn't have any, he said it again - several times.
Eventually, we went back to our speech therapy session and he said the same thing to the therapist. She found him some cheese puffs, and then asked for more, saying both "more" and "I want that" with his device, and with sign language, multiple times.
Hooray for breakthroughs!
