"Your baby weighs nearly 11 ounces and measures slightly less than 6 ½". She is actively kicking, but there is no particular amount in a 24-hour period. The average is about 200 kicks within 24 hours, but that range can go from 50 - 1000, depending on how active she is. Now you are most likely to feel your baby move when you are resting. She moves the most when you are sleeping (get used to those interruptions) because during the day, your movements rock her to sleep."
I just felt her/him kick as I pasted that. :)
"By week 20, your baby-to-be is gearing up for the next phase in his development—filling out. His organs are getting into their proper places. His kidneys are now in position with their familiar bean shape. His testes (or ovaries for girls) have reached their position. His brain continues to form and grow. His teeth are beginning to appear, and he can swallow."
I also read somewhere that he can hear now, and will put his hands by his ears if something startles him. :)
We go for our first ultrasound tomorrow. We're quite excited to find out the gender. We'll post that next week... we want to tell Chris' parents in person this weekend when they are here.
