Baby talk

Oliver now has three words:
"Ma"=Mommy
"Da"=Daddy
"Buh"=Buh-bye now.

He's added "buh" to his waving, so we're pretty sure he knows what he's saying. Or he knows that he's imitating what we're saying.
He has enjoyed an explosion of freedom in the last two weeks after mastering the slithery crawl. He also shimmies on his butt with one leg straight out to the side. He cocks his left leg out straight, curls his right, then starts bouncing up and down, propelling himself forward. He developed this technique after constantly ramming his head into cabinets and couches when trying to get close to objects on the floor. The "dropping" game is also a new favorite. Oliver has learned that when he drops things off the high chair they disappear and then someone will pick them back up.
