Libby is really beginning to babble more - I took this video to capture her current vocalizations. It used to be just grunts and such, but she is beginning to shape these sounds with her mouth and tongue:

A good friend (who is also a professional speech pathologist) had this to say about Libby’s babbling:
Her babbling right now is in the ‘expansion’ stage – lots of glide-like vowels. She is able to do this now because she is growing and her tongue isn’t taking up so much of her mouth anymore.
Later, in the next 3-4 months, you will start to hear consonant-vowel syllables. Those syllables will often be duplicated (bababa, mamama). That is called ‘canonical’ babbling. Caution: mama won’t have meaning yet but it soon will.
In 4-6 months you will hear adult-like intonation patterns and she will vary the vowels and consonants (di, ba, goo)
