Stitch has been saying "yeah" and "noooooo" for a while, as well as "wow" but these are very short words that could just be sounds, but a couple of days ago he said: "Thank you", clear as a day =)!
He loves learning from youtube videos, thats how he learned how to sing opera (the magic flute) and he learned "thank you" from Marnie on youtube!
My wife is now trying to teach him to say "good day".
Leroy has made progress in the speaking department as well, he doesnt say any words, but he has also started to sing opera, the same song from the magic flute as Stitch and I sing. He's great at it . I am very proud of him, it shows that he wants to sound like the rest of the flock =)!
