Jonathan was so excited, he started saying his first word that night:
Now his favorite usage is early in the morning, when he's awake and playful and Fabio is still asleep. He looks at Fabio and starts with a whisper "Dadda. Dadda. Dadadda," getting a little louder each time if Fabio doesn't wake up. Eventually he'll escalate up to a deafening yell, "DADDA! DAADDAA! DAADDAAA!" Until Fabio wakes up and plays with him, and he goes back to the normal volume he's using in the video.
It's the most effective alarm clock Fabio has ever had. How could anyone resist this little cutie calling for them, even at 5:00 in the morning?
