From May 2010:
At age 2.5, Gavin only said five words: Mama, Dada, go, up, and no.
But after he passed that age, he started talking in leaps and bounds. It's like the words were all in his head, but he wasn't going to try to say them until he finished learning how to climb the couch or drive his Cozy Coupe.
I was so excited I wrote all his words down (also, I needed to let the speech therapist know). I recently found the list. I won't list everything - I stopped keeping track at 177 words - but here are his first 50 words:
Bye bye (“buh-buh”)
