I get these weekly emails from babycenter and this week's says this: 21 weeks Your baby now weighs about three-quarters of a pound and is approximately 10 1/2 inches long the length of a carrot. You may soon feel like she's practicing martial arts as her initial fluttering movements turn into full-fledged kicks and nudges. You may also discover a pattern to her activity as you get to know her better. In other developments, your baby's eyebrows and lids are present now, and if you're having a girl, her vagina has begun to form as well. I love it! I love the comparison to food! I always tell my DH so all week he'll say "how's my little carrot?" sorry, feeling especially giddy today!
