Hi Gophie!
He can't say many words, so far: blanket (but he pronounces it as "branket"), doggie, car, dadda/daddy and then cracker.
Sometimes, I think he can say "what's that?" in his own way and a few other phrases but they aren't very clear.
His all time favorite thing is barking when he sees or hears a dog. He'll say "woof" "woof."
He does understand more and more everyday.
