Bill and I know how much Matthew understands when we have to spell his favorite things or activities like b-u-b-b-l-e-s and o-u-t and s-h-o-e-s and c-a-r and b-a-t-h in our conversations if he is within earshot and we don't want him to know what we're talking about. We can't even use signs because he knows sign language.
Matthew is a very vocal 33 month old but not fully verbal yet. He tries though. He babbles and hums and sings along (on key) to his favorite songs but he can't clearly say all the words that he knows yet. He really understands so much more than he lets on.
Vocabulary and Verbal Explosion
Five months ago, I listed 26 words that Matthew had consistent sounds for - his speech approximations for words he understood. He had around 140 words in his vocabulary. By the end of March, he spoke his first clear word for the first time. It was "bye". Since then, Matthew's vocabulary has expanded by at least another 39+ words. Within this past week alone, he has been trying to speak more words, with some words clearer than his previous approximations and some completely new verbalizations. Since he's been trying to say more words, we've stopped teaching him new signs. We still sign with him when needed but we mostly encourage talking instead of signing.
Here's a list of the additional words that he understands:
Here's his list of new spoken words/ speech approximations:
apple (apuh) - used to be "a"
bye (bye) - used to be "ba"
cat (tat) - used to be "aa"
choo choo (choo choo)
Daddy (dee) - used to be "da"
draw (daw - said like 'saw')
eat (tee) - used to be "t"
hello (ohw - like 'owe')
town (tow - like 'town' but without the 'n')
