a lot to say for oneself

Over the past few days her new thing is babbling to herself almost constantly. It began when she was eating and it sounded like she was muttering under her breath, and then she started doing it whilst playing with her toys, quietly though. This morning she woke us up (having been in with us since 4.30) doing it again but much more loudly. I think she's moving her tongue backwards and forwards to make a sound...its very cute! Tried to capture it on video but no success as yet - she just gets distracted.
