I am amazed at how fast Bud is developing. She seems completely different from even two weeks ago: then, she was just beginning to discover how her hands work, now, she is grabbing things "purposefully." (Apparently, the grab reflex should give way to "purposeful" grabbing.)
Another funny development is that Bud's discovering her voice (and her lungs). She makes these high-pitched squeal/laughs/screams. I do think these are social-laughs, as she does it at the appropriate times (for funny faces, funny sounds and when we play peek-a-boo).
Happy Birthday Bud!
