ER--YOUR TODDLER MIGHT BE ABOUT TO LEARN A NEW WORD
I thought this was interesting--and now I know what a speech 'disfluency" is:

"Stuck with a word on the tip of your tongue when talking to a toddler? Don't worry — a new study finds that hesitant speech may help the kid learn new vocabulary.

Language disfluencies, or the "ums" and "uhs" that pepper everyday speech, give young children a clue that the next word coming will be a new one, according to the study, which was published online Thursday (April 14) in the journal Developmental Science.

These clues may help children link new words with new objects in their environment.

"Very young children who don't have many words in their vocabulary have learned that disfluencies contain information that is useful in telling them what a speaker is going to refer to next," study researcher Celeste Kidd, a graduate student in brain and cognitive science at the University of Rochester, told LiveScience."

And I'm sure it works the same way for children who have Moebius Syndrome.  I believe that what slows down the speech development of children with Moebius is simple---they have to learn not just what to say...but then how to use the mouth they've been given to say it.

But they do learn that.
