He said what?

I meant to put this on one of the other three posts I made today, but completely forgot. Owen has said mama, dada and baba for months. Other things he has said, whether they have stuck or not have been:

bye bye
hey
duck
pup-pup
moo
daddy (although it sounds more like da-deeee)
mmm-hmm

And in the last few days he has mastered the use of "uh-oh".
