When our oldest was small, he didn’t speak. He didn’t start talking until he was almost 4. He had a way of getting anything he wanted without talking, though. He’d make a grunting noise and gesture in a way that made you know what he was after.
He was a very sensitive little guy and hated having too much attention focused on him. If any of our friends or family tried talking to him and he didn’t want their attention, he’d grunt and point at something away from himself. And they’d get distracted, trying to figure out what he was pointing to or what he wanted. He wasn’t stupid. He was purposely avoiding their direct attention by aiming it elsewhere. Like in this picture:

We put him in speech therapy when he was about a year and a half old, I think. The therapist taught him sign language as a way to lower his frustration level with not being able to speak, and to give him a way to communicate. The intent being to lessen the pressure on him to have to speak and make it easier for him to start.
He picked up the sign language quickly, and of course, these days there’s all kinds of books that show you how to teach babies sign language. And it’s really awesome.
But we moved when he was about two, and rather than find another speech therapist, I discovered the local school district had a free preschool program for kids with developmental delays, and tried to get him enrolled in that. It took time, though, and meanwhile he was content just to use sign language.
I don’t have many pictures of him signing, but here are a few I do have. (Yes, we didn’t cut his hair and let it grow all long and wild.)

Nathaniel signing “house.”

Nathaniel signing “little.”

Nathaniel signing “truck.”
When he was evaluated for the preschool program, they asked me how many signs he knew. I wasn’t sure and started listing them. When I got to 50, they said that was good enough. They were impressed he knew so many. Some I remember:
truck
car
bus
house
little
boy (which he used to refer to himself)
girl (which he used to refer to his younger sister)
mom
dad
bug
tractor
barn
eat
drink
more
train
sandwich
book
school
That’s all I can recall him knowing. But he knew lots more.
One funny thing: Catherine, one year younger than he, didn’t speak until he did. She picked up the sign language from him, though.
Oh, and he used to sign in his sleep. His two favorite things: “train” and “bug” (for VW bug).
The preschool was wonderful for him. Catherine later went into the same program (and for awhile they were even in the same class together). By the end of kindergarten, he was at his age level in speech ability.
And once he started talking, he stopped signing. He forgot it all rather quickly.
He’s 16 now and says he wants to take ASL for a foreign language requirement.
