That's the best approximation of the sounds Rebecca has been making lately.
Just in the past week, the variety of words sounds she produces has drastically increased. Who knows the reason why. It's pretty funny to listen to, and sounds more like real language. Right now, language would be nice, but it's fairly easy to determine her mood from intonations and behaviour anyway.
Rebecca has also begun to shake her head back in forth (à la "no"), but it doesn't seem to mean "no". I have no idea what it means. The mystery continues!
Rebecca has repeated her walking feat - again, only a few steps, but doesn't appear to be overly anxious to ramp things up. Fine by me!
