Gurgling?

This was Mr B's favorite sound there for a while - it kind of sounds like he's gurling water or something :) Sometimes it also sounds like he's saying "giggle" :) This video was really long so I shortened it - but it's funny because towards the end of the original video he slowly sits down from his standing position and I am so proud of him becuase he just learned how - my what a long was he's already come :)
