Cambria can finally sit up on her own!! Sitting up is a big milestone. She is so much happier now for it. Take for example, right now. She's sitting up hitting her Learning Drum and cooing. Before she could sit up she would lay on her back, roll on to her tummy and then get sad.
In the book Natural Childhood, they explain that "her limbs become further differentiated in their movements as she crawls, rises on to all fours and sits unsupported. This is usually attained by the eighth month. The setting position offers a new view of life. She can reach for, and grasp, objects and bring one moveable object into contact with another. She can beat the table with a spoon..."
I am pretty sure that Cambria knows two words now. "Mama" and "to nurse." The mama word is verbal and she says over and over "Mamamamama," usually when she's hungry. The nurse word is actually a baby sign where she curls her hand over and over. Usually she'll do both "mamamamamama" and curl her little hand.
