This week, Caitlin learned how to say "Mama" (or "Mum mum" or "Mom") - it varies what she says. For the first time yesterday, she indicated she was hungry by saying, "Um um um." Some other random words are starting to emerge: hi, bye, okay, up, down, and boy. Hi and bye seem to be the only consistent words. She is also getting braver and starting to let go when standing.
